95862 - Profile migration needs to record info about what it was migrated from

Status: VERIFIED DUPLICATE of bug 87619

(Core Graveyard :: Profile: BackEnd, defect)

Description

[Conrad Carlen (not reading bugmail)]

It's possible for the user to
1. Migrate a 4.x profile to a 6.x profile of the same name
2. Go back and use 4.x for a while, getting more mail
3. Try the next, better version of 6.x
4. The mail they collected in step 2 is not migrated and they're not happy

If we recorded, the profile from which a new profile was migrated, the mod date
of the newest item in the dir at that time, and a time stamp of when of profile
was last used by 6.x, we could remigrate (or ask the user if they want to)
remigrate the profile.

Another scenario in which this is helpful:
1. user starts up 6.x and chooses not to migrate, instead makes a new profile
called "fred"
2. now, at some later point, they want to migrate their old profile (also called
"fred")
3. they can't because, since we don't have this info and we don't want to
migrate profiles again and again, we don't migrate profiles which have the same
name as a new one.
