Upgrade 8.8.9 to 8.8.12

[snowymoountain]

Hi,

I would like to upgrade to 8.8.12 I have 100 Users and would like to use the new Address book feature as I host multiple organisations.

I'm on Centos 7 what is the best way to upgrade and apply patches (if necessary)

Also my system seems to be eating a lot of RAM I have webmin on and its showing virtually all physical RAM is used I have about 8 GB... about 500 MB is cache and about 300 free... if I look on MX toolbox the system response time is about 9ms ....

No users have reported any issues...

Thanks

Hello,

To upgrade from 8.8.9 to 8.8.12, just read carefully the release notes, take the usual measures (full backups, snapshots, etc) and proceed.

But in this particular case (8.8.12) there is a webmail nasty bug reported, you can read some threads reports in the forum. See viewtopic.php?f=13&t=66409

Are you referring to "Hierarchical Address Book"? As the time of this writing there's zero documentation about it. See viewtopic.php?t=66082

Acording the roadmap https://www.zimbra.com/support/support- ... lifecycle/, the next LTS version will be GA in july 2019, IMHO i'll wait fo it.

Actually I meant the new Calendar feature that allows delegation of Calendars to domains....
I have multiple domains on my system and don't want one domain really seeing the other...
