Migration from ZCS 5.0.18(32) to ZCS 7.1.2(64)

[marlonrstk]

Hello,
I have a centos 32 bits server with zcs 5.0.18 that is working very fine and i want to migrate to last version

of zimbra, because my version is very old and is still 32 bits.
I already tested but without sucessfull and I want to know if I am in the right way or not.
In my first tests i installed the zcs 5.0.18 (32) and migrate until 5.0.26_GA_3365(32) that worked, but when i try

to migrate to 6.0.0_GA_1802 i received a error.
I was Reading at zimbra Documentations i noticed that have there is problems between LDAP 5X.X and 6.X.X but i want to know what i can do to do this migration


Thanks for while.

This question has been answered many times in the forum. Go to the wiki (link at the top of this page) and search fro the article on moving a Zimbra server from 32bit to 64bit then follow the instructions in that article.

articles and i am trying to do this migration.

5.0.18(64) or migrate to releases more recents and after migrate to a 64 bits

My choice would be to upgrade your current version to the most recent one, check the release notes for details of the upgrade path. Make sure you take a full backup of your /top/zimbra directory structure (there are wiki articles and forum threads on backup procedures) then do the move to a new server.

Y was doing this on my virtual Box.

I upgraded my version from 5.0.18 to 5.26(32), but when i tried tu upgrade to 6.0.0 my server does not work more.

There is some tip to upgrade to 6.0.0 ?

Hello Bill
I got migrate from 5.0.18/32 to 7.1.3/64.
I read the release notes of all releases to do this tests and it worked.
Here is my way.

All steps i do in my VM to test.
1) First of all i prepared a new server with dns, sendmail stopped e all packages needed.


2)I installed a new server with centos 5.7/32 bits and zimbra 5.0.18(same version of my hot server).

cmd = ./install.sh --platform-override -s
3) remove the folder /opt/zimbra

cmd = rm -rf /opt/zimbra
4) rsync /opt/zimbra between server whith rsync

cmd= rsync .......
5) reinstall zimbra again with the same version

cmd = ./install.sh --platform-override
6) From here i installed the versions in a sequence that follow

5.0.18 to 5.0.19

5.0.19 to 6.0.2

6.0.2 to 6.0.14
cmd = ./install.sh --platform-override

7) when i finished the version 6.0.14 I Installed the ZExtra_migration_tool_1.0._1 and did a Backup of my server

with this tool.
8) I Installed a new Server with centos 5.7/64b and Zimbra 7.1.3/64b with zextra_suite_1.0.1.
9) at Zimbra admin page i restore the files that zextra_migration_1_0_1 generated.
10) finished.
Some considerations about this path?
This week i called to my support to ask for this procedures to migrate, and they coments that this way i can

not

back to a previous release if some problems happen.
There is a option to export all Mailbox/Agenda/Documents/Files/Tasks/Contacts and import at previous release?
There is a option to migrate without do this sequence of instalations?


Thanks for the help.
Marlon
