 In my case, before the reconstruct had finished, I had several problems
which might be not acceptable for large organizations.

For example, users could not move messages between folders in their
mailbox. I would consider this quite basic functionality, because
deleting a message (with most clients) also means moving it (to trash).
Functionality was back not before the reconstruct had finished
Apart from those we also had some weird problems with the message sort
order (using roundcube) before reconstruct was run.

We split the mailboxes reconstruction into 8 parallel jobs (IO on the
mailbox spool is the limit if you go from 2.3 -> 2.4/3.0). If you ran
the reconstruction online, once finished I would suggest to check again
all indexes version (some reconstruction jobs fail).
