ZCS FOSS 5 Migration to CentOS 5.6

[r8escjohn]

Doing a non-production box migration of existing Zimbra 5 install to new CentOS 5.6 Box (From OpenSUSE)
First, this migration guide is awesome!
Moving ZCS to New Server - Zimbra :: Wiki
Following this basically to the letter. First initial regular (for test) and -s install seem to go without any issues. Issue I have is after 2nd install after doing rsync of data I get this error:

Starting ldap...done.
Setting defaults...done.
Setting defaults from existing config...done.
Checking for port conflicts
Setting defaults from ldap...done.
dualvar is only available with the XS version of Scalar::Util at /opt/zimbra/zimbramon/lib/IO/Socket/SSL.pm line 30
BEGIN failed--compilation aborted at /opt/zimbra/zimbramon/lib/IO/Socket/SSL.pm line 30.
Compilation failed in require at /opt/zimbra/zimbramon/lib/Net/LDAP.pm line 998.

From doing searches I see this is a somewhat common error with CentOS. Any thoughts? I actually thought the fix was the uid/gid's being different and got a tad excited when I saw that and fixed, but no go....

Using this installer:
zcs-5.0.18_GA_3011.RHEL5.20090707164432]#

are you sure you installed all the dependencies on target machine before installing/upgrading

yum install nc which libidn curl fetchmail gmp compat-libstdc++-296 compat-libstdc++-33 compat-db libtool-ltdl perl-IO-Socket-INET6

also read this
[SOLVED] Still no fix ... " is only avaliable with the XS version at" issue

Raj, thanks for the reply! :->
Thought I was on to something as I did miss compat-db and I did need to update curl and curl-devel. But alas no luck and still get same exact error. darn.... Here is process I did for clarification-all ran with no error until end:
Removed Zimbra Install - /.install.sh --uninstall
Removed /opt/zimbra folder
Ran yum script you provided
Ran /.install.sh -s --platform-override
Ran /rm -rf /opt/zimbra
rsync'ed backup of /opt/zimbra from existing OpenSUSE server from external HD
Ran zmfixperms
Modified /opt/zimbra/conf/localconfig.xml with current zimbra uid and gid (Instead of 1000 was now 500 on CentOS box)
Ran /.install.sh --platform-override
Receive same above error towards end of Zimbra install..

Any other ideas? Thanks again!

Not sure if this will help or if it is any different, But I migrated zimbra 7.0 from centos 4 to centos 5 about two months ago. I followed this guide exactly and didn't have any problems.

Ok, this issue has me way confused as I look more into it......
IF I remove all Zimbra 'stuff' and do a standard install on my CentOS 5.6 box using the zcs-5.0.18_GA_3011.RHEL5.20090707164432 installer
/.install.sh --platform-override
it WORKS and I can even sign into Admin console, add users and then sign in as that user.
Problem with the 'XS version of Scalar:Util' ONLY crops up if I try to do a migration as described in the WiKi from my OpenSUSE 10.3 backup.

What am I missing?

[raj]

Just for the sake of it try higher version in the last step..like latest 6.0 ( or 7 if you like)
i think its the PERL issue which is conflicting.
OpenSUSE PERL is differnet than CENTOS PERL.

i know zimbra ships with its own version of PERL and in older verions there was an issue.

Raj,
Thanks for the info and responce, but would I be able to migrate using my Zimbra 5.0.18 backup if I loaded like say ZCS 6?

[raj]

yes..
1) backup - rsync from SOURCE server (after services stopped)
2) install SAME version of zimbra with -s
3) copy over your rsync to TARGET server
4) fix file permissions
5) Run installer with latest version and do UPGRADE when asked

* above instructions dont take care of 32 bit to 64 bit conversion..you need to read that on forums and wiki
