Migrating ad-set budgets to campaign budgets without a reset

Migrating ad-set budgets to campaign budgets without a reset

The step-by-step to move from ad-set budgets (ABO) to campaign budgets (CBO) and keep learnings.
— Step 1: only migrate ad sets already past learning (50+ optimization events/week).
— Step 2: duplicate the winning ad sets into one fresh campaign — don't edit budget on the live one.
— Step 3: cap initial campaign budget at the sum of the old ad-set budgets, not higher.
— Step 4: hold 72h before judging; consolidation always dips day 1-2.

Post-migration CPA settling basis, 31 accounts: recovers to baseline by day 3 in top quartile / day 5 median / never in bottom (over-consolidated).

Read: migrate winners, never the whole campaign — CBO redistributes away from your weak ad sets, not toward fixing them.
