Questions around moving from 2.2.12 to 2.4.12

[Manel Gimeno Zaragozá]

Hello,

I'm doing almost same migration, from old cyrus (2.2.12) to new version (2.4.13) and I'm using "imapsync" utility in Centos6 to "copy" all data. After some reading and attempts I have a "fast" sync method to copy the data from old server to new one.

Regards.
