imapsync always loses data
never saw this, be carefull by anounce such myths
It is a fact. Imapsync works over IMAP only and IMAP protocol
does not even support transferring all data. At most at least UID
numbering will be lost and end users need to invalidate their
local caches.but using "looses data" might others think it also may fail with imap, so be more detailed next time
UID number is also data that is saved on the IMAP backend. If that
is lost then it's "lost data".Sami
Sorry i migrated terrabytes of mail with imapsync and never had a problem, it works as designed, also with maildir rsync did a good job, what never worked as it should was dsync ,cause of bugs ,that may changed now
so this is my answer to topic
"Best way to move mail from one server to another"
https://imapsync.lamiral.info/FAQ.d/FAQ.Duplicates.txt
Seems to use UIDs so that 'data' isn't lost.
