Migration Assistant Caveat
Authored by: jecwobble on May 03, '07 11:53:10AM
I was thinking Migration Assistant in this case would work, too.

In a related UID situation, I had to change UIDs rather than changing user permissions. I had two computers (A and B for illustrative purposes). I had the first and only account on A and the first of four accounts on B, so I had a UID of 501 on both. I would mount one from the other and access my home folder on each without problems.

I got another computer, C, to replace B. I migrated the four accounts from B to C. When I mounted C from A, I could not access my home folder. Instead I could access one of the other three user's home folder.

The reason appears to be because Migration Assistant created new users on C alphabetically according to the user names on B. A user with a name that came before mine alphabetically was given UID 501, while I was given 502 (the opposite of what UIDs were on computer B). I ended up changing user 501 to 505, then changing my user to 501. Now I can properly access just my home folders on each.

Moral of the story: don't assume that UIDs are preserved while using Migration Assistant.
