Hi Bron, I'm currently testing the upgrade path from 2.3.16 to 2.4.17. Everything is smooth so far, mailbox indexes were upgraded automatically after starting 2.4.17 for the first time:
-------------------------- Dec 18 13:48:00 ctl_cyrusdb[14851]: checkpointing cyrus databases Dec 18 13:48:00 ctl_cyrusdb[14851]: done checkpointing cyrus databases Dec 18 13:48:00 cyr_expire[14850]: Index upgrade: user.admin (10 -> 12) Dec 18 13:48:00 cyr_expire[14850]: Index upgrade: user.admin.Entw&APw-rfe (10 -> 12) Dec 18 13:48:00 cyr_expire[14850]: Index upgrade: user.admin.Gel&APY-schte Elemente (10 -> 12) Dec 18 13:48:00 cyr_expire[14850]: Index upgrade: user.admin.Gesendete Elemente (10 -> 12) Dec 18 13:48:00 cyr_expire[14850]: Index upgrade: user.cyrus (10 -> 12) Dec 18 13:48:00 cyr_expire[14850]: Index upgrade: user.mueller (10 -> 12) Dec 18 13:48:00 cyr_expire[14850]: Index upgrade: user.mueller.Entw&APw-rfe (10 -> 12) Dec 18 13:48:00 cyr_expire[14850]: Index upgrade: user.mueller.Gel&APY-schte Elemente (10 -> 12) Dec 18 13:48:00 cyr_expire[14850]: Index upgrade: user.mueller.Gesendete Elemente (10 -> 12) -------------------------- For the fun of it (doing it for science!) I downgraded again to 2.3.16 while keeping the new index files. Every access to the mailbox via IMAP was blocked with "Future index version xxx". Good. -> So the indexes are protected against a downgrade without a reconstruct. Will mailboxes.db / annotations.db also stay fine after a downgrade? I don't think there are any data structure differences between 2.3.x and 2.4.x in there but I thought I'd better ask. Cheers, Thomas
