Just wanted to share a successful migration for a customer's ZCS with 150 users from RHEL 32bit to 7.0.1 64bit.
- from RHEL 5 32bit to 64bit, keeping the same ZCS version 6.11 based on Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki
- from ZCS 6.11 to 7.0 by the book, while doing this I noticed the tweet that 7.0.1 came to live
- from 7.0 to 7.0.1 by the book, after contacting the client for the clearance to upgrade
All went smoothly.
Have a nice day!
