Did calculating the quota change from 2.3 to 2.5?

No, IMAP doesn't know about deduplication;  so imapsync between two
servers dededuplicates.  imapsync may also repair damaged or missing
message headers - meaning the messages are no longer are the same - so
a tool like hardlinks will not return you to the same count in du as on
the old server.

And then there is the [virtuous] issue of delayed expunge.
