Maybe so, but i would think the imapsync --regextrans2 option was ment
for this kind of scenario.

Flags, state and Dates remain unchanged. No problem there.

Nope. Even something like this works. Translates to 'Humlebæk Auto' :)

	--regextrans2 's#^Humleb&AMMApg-k Auto$#Arbejde/Humleb&AOY-k Auto#

All is good, except for the missing intermediate levels in the structure.

Suggestions to other cool imap migration tools, up to the task, are also welcome ;^)
