Migrating PPC platforms looks simple until you’re in the middle of it.

Lose account ownership, miss a legacy script, or skip a backup, and suddenly you’re facing broken tracking, underperforming campaigns, and frustrated stakeholders.

What should have been an upgrade turns into weeks of damage control.

In this guide, we’ll show you the most common (and costly) migration mistakes and how to avoid them.

We’ll also share how Optmyzr helps advertisers and agencies safeguard data, preserve automations, and keep campaigns running smoothly so you can switch platforms with confidence.

Mistake #1: Failing to secure account ownership before migrating

One of the biggest risks when switching PPC platforms is relying on vendor-owned MCCs (manager accounts) or business accounts. If your old vendor controls account ownership, you could lose access to valuable historical data, face gaps in reporting, or encounter compliance issues.

Beware of agencies that restrict account access.

If you decide to cancel, some may not return your accounts, leaving you without your data or campaign history. Always ensure you maintain full ownership so you stay in control no matter who manages your ads.

The Fix:

Before starting a migration, it’s critical to:

• Transfer all accounts into company-owned MCCs for full control
• Confirm and document all user permissions so nothing slips through the cracks
• Archive your current account structures (campaign hierarchy, custom labels, bid adjustments) to ensure continuity

How Optmyzr helps

Optmyzr connects directly through your own Google Ads, Microsoft Ads, or Facebook Ads manager account login.

This ensures from day one that you own the account, not a third party.

And because Optmyzr’s connection is secure and limited to your credentials, only you can make changes to your campaigns.

Our onboarding team guides advertisers through the verification of ownership and permissions, ensuring migration starts from a position of control.

Mistake #2: Forgetting to audit and remove legacy scripts & rules

When migrating to a new PPC management platform, many advertisers overlook the scripts, rules, and alerts left behind by their previous vendor.

These “ghost automations” not only clutter the account, but they can also actively conflict with new workflows, causing duplicate conversions, incorrect budget pacing, and even pausing campaigns.

The Fix:

To ensure a clean platform transition, it’s essential to:

• Identify and remove vendor-installed scripts, rules, and automated alerts
• Review all conversion goals for duplicates or inflated tracking that may skew reporting
• Standardize tracking parameters before cutover to avoid conflicts post-migration

How Optmyzr helps

Instead of relying on outdated scripts or leftover rules from your previous vendor, Optmyzr gives you full control with the Rule Engine. Before migrating, we recommend writing down the logic of your existing rules. Our Customer Success team can then help you rebuild them cleanly in the Rule Engine.

Here’s what the RE covers:

• You can rebuild essential automations in a clean, transparent way, without hidden scripts running in the background.
• Rules are fully customizable, covering everything from budget pacing and bid adjustments to keyword and ad management, so you can replicate what worked before and improve what didn’t.
• Unlike legacy scripts, Rule Engine rules are easy to audit, update, and scale across accounts, reducing the risk of conflicts or duplicate automations.

Automation Schedules further helps you quickly access automation settings, monitor performance, and even jump directly into the main tool if you need to make manual changes right away.

Mistake #3: Not backing up historical data and custom dashboards

Historical performance data is the backbone of smart optimization. Yet during migration, many advertisers assume their new platform will handle all data transfers seamlessly.

The risk? Incomplete imports, missing dashboards, or lost attribution models make it harder to benchmark performance, optimize effectively, or reassure stakeholders that continuity has been preserved.

The Fix:

Even if your new platform offers import features, it’s essential to:

• Export and archive key performance data (campaign metrics, audience segments, dashboards)
• Preserve conversion history and attribution models for apples-to-apples performance comparisons
• Ensure client- or stakeholder-facing reports remain consistent during and after the transition
• Save PDFs of your existing reports so they can be quickly duplicated in Optmyzr’s Report Designer

How Optmyzr helps

Optmyzr makes it simple to preserve and re-create the insights you depend on:

• Report Templates & Custom Dashboards: Before migrating, you can set up client- or stakeholder-facing dashboards in Optmyzr, ensuring continuity even if your old vendor’s reports don’t transfer.
• Data Archiving: With integrations across Google Ads, Microsoft Ads, and Meta Ads, Optmyzr can pull in your historical performance data so you don’t lose benchmarks or attribution models.
• Seamless Reporting Transition: Rebuilding reports in Optmyzr helps you maintain apples-to-apples comparisons and avoid communication gaps with clients and stakeholders.

With AI-generated Reports, you can even go beyond templates, creating custom narratives, visuals, or summaries from a simple prompt.

That’s how Optmyzr ensures your history, insights, and reporting consistency are not lost in migration.

Mistake #4: Skipping feature mapping when choosing a new platform

Not all PPC management platforms are created equal. A common mistake during migration is selecting a tool without first confirming that it supports critical workflows, from automation and bulk edits to reporting and cross-account management.

Teams then discover missing capabilities after migrating, which leads to workflow breakdowns, wasted time recreating processes, and costly performance setbacks.

The Fix:

To avoid surprises, make sure to:

• Map your current features (automation, reporting, bid adjustments, bulk edits, labeling, workflows) to the capabilities of the new platform.
• Use your free trial to test essential workflows and book a training session to confirm the software supports your needs.
• Document which features are “must-haves” vs. “nice-to-haves” so you don’t compromise on essentials.

How Optmyzr Helps

One of the biggest fears in a migration is discovering after the switch that the new platform doesn’t support a workflow your team depends on. That’s where Optmyzr stands apart.

Not only does Optmyzr cover critical workflows like automation, bulk edits, advanced reporting, and cross-account management, but we also maintain a comprehensive Help Center with summaries of every supported tool, organized by category.

At any time, you can check exactly which workflows Optmyzr supports and how they work across Google Ads, Microsoft Ads, Amazon Ads, and Meta Ads.

We also treat customer feature requests as a core part of our product roadmap.

If there’s a capability you rely on that isn’t yet in Optmyzr, our product team takes your request seriously.

Many of our most impactful features came from advertisers and agencies like you.

So instead of being locked into a rigid tool, you get a platform that evolves with your needs, ensuring you’re never stuck without the features that drive performance.

Mistake #5: Underestimating training & knowledge transfer needs

Even the most powerful PPC platform won’t deliver results if the team managing it doesn’t feel confident using it. A common mistake during migration is assuming teams will “figure it out as they go.”

In reality, unfamiliar terminology, new workflows, and different reporting formats can slow adoption, create errors, and cause unnecessary performance drops in the early weeks.

The Fix:

Successful migrations build in structured knowledge transfer:

• Conduct training sessions for all team members who will use the new platform.
• Provide quick-reference guides for common workflows and tasks.
• Map old terminology/workflows to the new platform’s equivalents so transitions feel seamless.
• Assign a team champion who can go deep during the trial, and then train others and answer questions
• Set up a Slack or internal chat channel during the trial to centralize team questions, discoveries, and tips
  

How Optmyzr helps

Optmyzr is built with customer enablement at its core. Beyond the platform itself, we provide extensive resources to ensure your team transitions smoothly and confidently:

• Step-by-step guidance: A detailed Help Center knowledge base with step-by-step guides.
• Blueprints: Ready-made workflows that not only save time but also serve as a training tool for onboarding new team members, helping them learn the software faster.
• Always-available learning: Click the “?” icon in the top right corner of any tool to instantly access videos, user guides, and tutorials tailored to what you’re viewing, making the platform more self-explanatory and easy to adopt.
• Responsive support: A responsive customer support team consistently praised by advertisers and agencies for quick, effective assistance
• Hands-on education: Ongoing educational series like Learn with Optmyzr and the Automation Layering Masterclass, often conducted in collaboration with customers to showcase real-world use cases
• Rich learning library: A library of tutorials, webinars, and best-practice resources to help your team ramp up faster and avoid performance dips

With these resources, advertisers not only migrate to a new PPC tool, but they also gain a partner invested in their success.

Mistake #6: Ignoring early performance data post-migration

After migration, some advertisers take a “set it and forget it” approach, assuming campaigns will stabilize on their own. The reality is that even small differences in tracking, automation, or reporting between platforms can lead to unexpected performance shifts.

Waiting too long to react means wasted budget, lost conversions, and missed opportunities to reassure stakeholders that the transition is under control.

The Fix:

A strong migration plan should include active monitoring:

• Set fresh performance benchmarks immediately after migration.
• Track daily for the first 30 days to catch anomalies in bidding, budgets, or audience targeting.
• Be ready to adjust budgets, bids, and targeting based on the new platform’s insights and pacing.

How Optmyzr Helps:

Optmyzr’s Anomaly Alerts (Auto Alerts) give advertisers peace of mind by monitoring key metrics automatically across Google Ads, Microsoft Ads, and Facebook Ads.

Without any setup, Optmyzr alerts you when spend, clicks, or impressions deviate significantly from expected trends; whether it’s a sudden spike or an alarming drop.

• Default anomaly alerts for cost, impressions, and clicks are built in. These alerts can also help flag issues that might otherwise go unnoticed—like when a client’s credit card fails.
• Feed anomaly alerts notify you when large portions of product feeds are disapproved.
• Alerts are delivered automatically via email or Slack, so issues can be addressed immediately.

Combine anomaly alerts with Optmyzr’s Rule Engine to set custom thresholds, guardrails, and recurring checks.

Add extra layers of protection with the Anomaly Detector Script and run the PPC Account Audit to find deeper issues that may be holding performance back.

That’s the kind of proactive monitoring you need in the first 30 days post-migration.

It will help you catch disruptions early, keep stakeholders reassured, and protect performance continuity.

FAQs

1. What is PPC platform migration?

A. PPC platform migration is the process of moving your paid search and advertising campaigns (Google Ads, Microsoft Ads, Facebook Ads, etc.) from one management tool or vendor to another. It includes transferring account ownership, historical data, tracking setups, automations, and reporting dashboards to ensure continuity.

2. Why is PPC migration risky?

A. Without proper planning, migrations can lead to lost performance history, broken tracking, duplicate or missing automations, campaign downtime, and reporting gaps. These disruptions can harm ROI and undermine client or stakeholder trust.

3. How do I migrate PPC accounts safely?

A. The safest approach is to follow a structured migration plan:

• Secure account ownership under your company’s MCC.
• Audit and remove legacy scripts and rules.

6. How do agencies manage PPC migrations for multiple clients?

A. Agencies need a standardized process: ownership audits, clear communication with clients, consistent data backups, and training resources for account managers. A checklist and migration framework help keep multi-account transitions organized.

7. How long does a PPC migration take?

A. Timelines vary based on the size and complexity of your accounts, but most migrations can be completed within a few weeks. Running parallel campaigns during this time ensures performance stability.
