Upgrade Path from ZCS Ubuntu 8.04 (6.0.8) to Ubuntu 10.04 (6.0.10)
What would be the correct way to upgrade ZCS Ubuntu 8.04 (6.0.8) to Ubuntu 10.04 (6.0.10)? Do I need to upgrade to ZCS Ubuntu 8.04 (6.0.10) first, then to ZCS Ubuntu 10.04 (6.0.10)? Or straight away upgrade ZCS Ubuntu 8.04 (6.0.8) to Ubuntu 10.04 (6.0.10) will do?
ZCS Ubuntu 8.04 (6.0.8) to Ubuntu 10.04 (6.0.10) MIGRATION: NEW HARDWARE
Sorry if I'm hijacking this thread:
A couple days ago, one of my ZCS 6.0.8 on Ubuntu 8.04 LTS systems had a RAID1 complete failure with a couple of 1 month old 1TB Seagate SAS Drives (Part Number ST31000640SS 9EF248-003).
That's 3 of those drives that have failed on me now.....
I'm also having serious doubts about the RAID controller as well.
Thankfully the disaster recovery to a temporary server worked fabulously well. :-)
Anyway, it looks like we're going to have to go for a new server, so I thought I'd upgrade to Ubuntu 10.04 LTS and ZCS 6.0.10 at the same time.
So, I'm wondering if this would work on a new server:
Build OS: Ubuntu 10.04 LTS.
Install dependencies and split DNS.
Copy in entire /opt/zimbra from old UB8.04 server DO NOT START IT.
Run upgrade install of ZCS 6.0.10
Whaddya think ?
Many thanks !
