sounds familiar.

yes, you can simply change it ... in principle (and it worked just fine
for me, multipe times).
make sure that the message UIDs still match despite the changed
UIDVALIDITY - if they don't, you lose all messages.
use some online-imap client which can display UIDs (i think i used
thunderbird, because i had it set up anyway; i suspect mutt can do that
as well) to take some random samples (if the UIDs changed, all of them
would).

the lower-risk approach is deleting the state files, so mbsync
propagates the messages both ways again. then use D~= in mutt to throw
out the dupes.
