Migration using imapsync

+ I assume that you build the imapsync command by hand and type it in.
+ I assume that you have a copy of the imapsync command you used in a
file called '/tmp/cmd'.
+ I assume that you have one regextrans2 per line.
+ I assume that you only have one level of subfolders.

You can extract a list of "parent folders" from 'cmd' thusly (storing
them in '/tmp/parents'):

$ cat /tmp/cmd |sed -e 's!.*$#\(.*\)/.*!\1!' |sort -u > /tmp/parents


You can then create those folders on the uw-imap server by touching the
files:

$ cat /tmp/parents | xargs -n1 -d "\n" touch


You can then resync and the missing folders should be created.

Alternatively, instead of touching the files, you can build commands to
pipe to cyradm that will create the folders.
