<br>
I want to ask if any of you has done a migration from a single storage <br>
to multiple back-end storages and what is the best strategy for folder <br>
hashing that you use.<br>
<br>
Using something like %H or %M how do you predict where the mail will end <br>
up in order to move the existing folders ?<br>
<br>
Thank you !<br>
