Hi guys, I'm running Cyrus Imap 2.4.16 on Debian 7 (x86) 32 bits and I need to migrate to 2.4.17(nocaldav) on Debian 8 (x86) ** 64 bits **. I've been reading some articles (like this one, which is 6 years old: https://cynici.wordpress.com/2010/12/06/how-to-migrate-32-bit-cyrus-imapd-mailboxes-to-64-bit/ ). My question is: is it really needed to convert .db from skiplist to flag, and then back to skiplist , as suggested by many articles? (or even rebuild mailboxes like in last pointed article). Both machines are x86, being the only difference 32 vs 64 bits (endianness is same, etc). I did a quick test simulating the migration, by simply just copying /var/lib/imap, /var/spool/mail and /var/spool/sieve. It seems it worked fine (or at least I couldn't find any problem when running imap with the migrated data). But I'd need your confirmation this should be sufficient and I won't find problems in the future. I also played with db conversions (skiplist -> flat -> skiplist) and I have some questions: - I converted annotations.db (skiplist) to flat and then back to skiplist. It passed from 11K to 144 bytes (both skiplist)!!! Is it normal? - I did same exercise obtaining new skiplist db in both machines from a same flat. I got a vey similar (but not exactly the same) result .db in both 32 & 64 bits (some minor bytes may change but it didn't seem like big differences/changes). Maybe some different metadata (I mean not important), or I should concern about it? - apart from .db's from /var/lib/imap, should I worry about other skiplist like .seen files in /var/spool/mail? Sorry if there are too much questions but this migration is important, I cannot loose any data (email data + email metadata: read marks, etc). Please, advise! Thank you so much in advance and have a nice day! -- Saludos, -Román ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
