FWIW, we had a similar problem with the upgrade.
The issue is being discussed on a cyrus list at
https://cyrus.topicbox.com/groups/info/T3e85440ddbb44ec6-Maf769decd0dd45d4572145b8
TLDR; it appears that this might have been caused by 3 new cyrus
utilities not being included in the debian package:
relocate_by_id
cyr_ls
cyr_cd.sh
Also, it looks like we will need relocate_by_id to be able to recover
several of our mailboxes that we have been unable to manually move to
the new storage introduced by .
Sincere regards.
