Zimbra 7.2.1 to 8

[dirtyal]

We have a 50 account license running a Zimbra 7.2.1.
I just installed Zimbra 8 and tried to import the backup from 7.2.1 using zextras 1.6.1 and a get this exception in the log.
The zextras on 7.2.1 is also version 1.6.1 and it has a license, the zextras in Zimbra 8 is a trial license.
Zimbra 7.2.1 in running on centos 5 64bits and Zimbra 8 is running on CentOS 6 64bits.

Any idea what could be wrong?

Tks.

Hello diryal,

the "java.lang.OutOfMemoryError: Java heap space" means that Java ran out of memory and couldn't complete the operation...
What are the specs of your server? Also, Phisical or Virtual?

Have a nice day,

Hello Cine,

it is a VM, I increased the memory form 4GB to 8GB and the same exception happened again. Any tips?

Hello Dirtyal.

A couple of checks off the top of my head:

* Check the JVM options in Zimbra (run the following command as the zimbra user):

zmlocalconfig mailboxd_java_options mailboxd_java_heap_size mailboxd_java_heap_memory_percent

* Make sure that the RAM of the VM is not limited by the hypervisor (if you have a 2Gb limit increasing the ram from 4 to 8Gb would only worsen the situation)

* Keep an eye on your system resources during the restore with htop to see if there is any process using an abnormal quantity of ram

[dirtyal]

JVM options follow

[root@mail ~]# su - zimbra
[zimbra@mail ~]$ zmlocalconfig mailboxd_java_options mailboxd_java_heap_size mailboxd_java_heap_memory_percent
Warning: null valued key 'mailboxd_java_heap_memory_percent'
mailboxd_java_options = -server -Djava.awt.headless=true -Dsun.net.inetaddr.ttl=60 -XX:+UseConcMarkSweepGC -XX:PermSize=128m -XX:MaxPermSize=128m -XX:SoftRefLRUPolicyMSPerMB=1 -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCApplicationStoppedTime -XX:-OmitStackTraceInFastThrow -Djava.net.preferIPv4Stack=true
mailboxd_java_heap_size = 256

I will install HTOP and check this out.
There is no limit comming form the hypervisor, at least I did´t find any.

I increased java heao memory and it is working, but, first, I got the message, Caused by: [ExternalRestore] Backup too old for Trial Version., I then installed my lincense on this HW to try import the backup from my production server, then got this error
ZxBackup Thread: Operation ignored since ZxBackup license is not valid

How can I import the backup on my zimbra 8 test server to test if all itens are ok before I can actually to a migration? Tks.

Hello dirtyal!

Is your license a "Perpetual License" bound to Zimbra 7? If so, please send me a Private Message with your ZeXtras Store username, I'll be glad to provide you with an Extended Trial License in order to run your tests...

Have a nice day,
