Migration Wizard logs

It's been awhile since I've used the Admin migration process in Integrity, but my recollection is that unless you manually save the output from the screens that are generated when the admin migration wizard is run, I don't believe it retains that info in any way. 

It looks like you may be able to capture some of this info, if you turn on audit logging, but it's not the same report info though:

Maybe one of the ALM folks will chime in here, or you can open a Support case, to inquire with them further.

From troubleshooting a migration problem with PTC Support more than a year ago, I think the table that's generated every time you migrate is kept until the next time.

Its a mapping table, though, so you need multiple joins to other tables to make it readable and I'm not sure it's worth the time.

The table name is AdminIDMap.

Reading the title of your post, I notice the word "logs" and I wonder if you simply want to have a log of the migration done instead of all the differences at that point in time. If that's the case, audit logging is the way to go.
