Comparing data from separate Google Analytics accounts
I am working on a multi-site migration - four domains that will be merged into one new domain - and have a question about Google Analytics reporting after the migration has been completed.
If we install a new tracking code on the new domain, what's the best way to compare that data with the pre-migragion websites? Would it be possible to enter the data from more than one Google Analytics account in Google Data Suite?
Thank you in advance!
