DSA to AI Max Migration: The Operator's Pre-Upgrade Checklist

If you run paid search, the decision has already been made for you. Google announced that Dynamic Search Ads are being upgraded to AI Max in 2026, not as an opt-in, but as an auto-migration into the new campaign type. Your DSA to AI Max migration is happening whether your account is ready or not.

The operator's job, between now and your migration date, is narrow and concrete: export the history you'll lose, set the steering controls you'll need on day one, and define the 30-day window where you decide if AI Max keeps your account or restructures it.

This is a checklist, not a hot take.

TL;DR

• Google is force-upgrading Dynamic Search Ads to AI Max in 2026, every DSA account is in scope, not just opted-in ones.

• Export search terms, converting URLs, and negative lists before your migration date, DSA-specific history doesn't all carry over cleanly.

• AI Brief guidelines and text disclaimers, announced April 30, 2026, are your main levers to keep messaging on-script post-migration.

• Lock brand exclusions, URL exclusions, and disclaimers on day one, before the system starts learning on your spend.

• Budget for a 30-day monitoring window where queries, destinations, and pacing get reviewed weekly, not monthly.

1. What's actually happening, and who's affected

Google's announcement is short on dates and long on direction: Dynamic Search Ads, the campaign type that crawled your site and matched user queries to your pages, is being folded into AI Max for Search throughout 2026. Migrations are rolling, not simultaneous. If you have a DSA campaign live today, you'll get a migration window, typically 30 to 60 days of advance notice in our client accounts, and then the upgrade runs whether you've prepared or not.

Who's affected: every advertiser running DSAs as of mid-2026. That includes the ecommerce account using DSAs to catch long-tail product queries, the lead-gen account using them to pick up new service pages, and the publisher using them as a cheap discovery layer. If your account has the word "Dynamic" anywhere in a campaign name, you're in scope.

The vendor case for the change is conversion lift. Google's published AI Max results cite roughly 14% more conversions on average, up to 27% for accounts heavy in exact and phrase match. Those are vendor-reported figures, useful as a directional signal, not as a forecast for your account. Validate against your own pre- and post-migration conversion rate before you believe the lift applies to you.

2. Settings that don't map 1:1

The migration documentation suggests a clean port. In practice, three controls behave differently enough to matter.

Page feeds in DSA were a hard whitelist, the crawler only targeted URLs in the feed. In AI Max, page feeds become a signal among signals. The system can, and does, expand to other URLs on your domain unless you explicitly restrict it via URL exclusions. If you've been using page feeds to keep DSAs off your careers page or your investor relations section, that protection doesn't survive the upgrade by default.

4. Day-one controls: AI Brief, brand exclusions, disclaimers

The day your account flips to AI Max, the system starts learning on your spend. The controls you set in the first 48 hours shape that learning more than any optimization you do in month two.

Google introduced new steering controls on April 30, 2026: AI Brief guidelines and text disclaimers that persist through Final URL expansion. These are your two main levers for keeping messaging on-script.

5. Budget and bidding through the transition

Don't change bid strategy in the same week as the migration. Two variables changing at once destroys your ability to attribute movement to either.

Hold whatever bid strategy your DSA campaigns used, Target CPA, Target ROAS, Maximize Conversions, for the first 14 days post-migration. The system needs a baseline to learn against. If your DSAs were on Maximize Clicks, switch to a conversion-based strategy before the migration, give it 14 days to stabilize, then let the upgrade happen.

For accounts under $10k/month in paid search spend, the small-business AI Max playbook covers tighter constraints worth applying here.

6. The first-30-days monitoring plan

Migration day is not the finish line. The 30 days after it determine whether AI Max keeps the account or you restructure into a tighter, more controlled setup.

Review cadence:

• Days 1-7: check daily. Watch query reports for off-theme matches, URL reports for unwanted destinations, and spend pacing against your cap. Add negatives and URL exclusions same-day.

• Days 8-21: check every 2-3 days. The system is learning. New query patterns will appear. Triage: add to brief, add to exclusions, or let it run.

• Days 22-30: weekly review. Compare conversion volume and cost-per-conversion to your pre-migration 30-day baseline. This is the decision point.

7. When to bring in outside supervision

For most accounts under $5k/month in paid search, the checklist above is enough to run yourself. The work is mechanical, and the levers are documented.

Above $15k/month, the math changes. A 10% spend pacing swing on a $20k budget is $2,000 that has to be defended to someone. The case for outside supervision is straightforward: you want a second set of eyes during the migration window, structured reviews at days 7, 14, and 30, and someone whose job is to add the negative before the spend compounds.

What that should cost: a defined-scope migration supervision engagement typically runs in the range of one to two weeks of senior paid-search time, billed as a fixed project rather than a retainer. If a vendor wants to lock you into a 12-month contract to supervise a 30-day migration, that's the wrong vendor. We structure ours as a fixed-scope sprint with a clear handback. Details on our approach are on the paid ads service page.

FAQ

When are Dynamic Search Ads being retired?

Google has not published a single global cutover date. The DSA-to-AI-Max upgrade is rolling through 2026, with individual accounts receiving migration windows of typically 30 to 60 days of notice. Treat "dynamic search ads retired 2026" as a year-long process, not an event, your specific date is in your account notifications.

Is AI Max the official DSA replacement in Google Ads?

Yes. Google has confirmed AI Max for Search is the campaign type DSAs are being upgraded into. The DSA replacement in Google Ads is not a separate product, it's the AI Max campaign type, which absorbs DSA functionality while expanding matching across queries, URLs, and ad copy generation.

Will my DSA negative keywords and exclusions carry over?

Negative keyword lists carry over. DSA-specific negative dynamic ad targets, the URL-based exclusions, need to be rebuilt as URL exclusions in the new AI Max campaign. Export both before your migration window opens. Plan to spend an hour re-creating URL exclusions on day one of the new campaign.

How much conversion lift should I expect after the dynamic search ads upgrade to AI Max?

Google's vendor-reported results cite roughly 14% more conversions on average, up to 27% for exact and phrase-heavy accounts. Treat these as directional, not as a forecast for your account. Validate against your own pre- and post-migration 30-day conversion rate before assuming the lift applies.

What's the single most important thing to do before migration?

Export your search terms report with 18 months of history, segmented by campaign and ad group. This is the artifact most likely to lose granularity in the upgrade, and the one you'll need most when AI Max starts matching queries you haven't seen before. Everything else on the checklist matters; this is the irreplaceable one.

Your move this week

Block two hours on Thursday. Export the search terms, converting URLs, and negative lists from every DSA campaign you run. Save them somewhere that isn't Google Ads. That's the one action that costs nothing and protects everything downstream.

If you want a second set of eyes on the migration window itself, tell us what's in your account and we'll tell you whether supervision is worth the scope.
