How to maintain historical reputation data during domain changes?

Preserving reputation data during changes:

Archive old domain data:

Export postmaster tool data

Save historical metrics

Document blocklist history

Keep bounce and complaint records

Transition documentation:

Record reason for change

Note what was learned

Document new domain setup

New domain baseline:

Establish fresh metrics from day one

Track warmup progress

Compare to old domain learning (not reputation transfer)

Learning application:

Use old domain lessons to avoid repeating mistakes

Better practices on new domain

Historical data informs strategy, not reputation

Reputation does not transfer. Lessons learned should.
