Continuing my planning to change from 32bit to 64 bit

[p_nyet]

A few days I've a posting questions about possibility change Zimbra from 32 bit to 64 bit

Phoenix already answered my questions and refereing to many links.
I do something to my server project's with following instructions from zimbrablog [import and export ldap].

I've finished import wthout error message, but i getting a many problem...
I just to known what wrong and may be my mistake, also how to fixed?

Ok, this is my scenario:

my active server called as mail and my project server called as mail2

1. I've finished import ldap.bak from mail to mail2 without error message
[zimbra@mail2 ~]$ ./openldap/sbin/slapadd -F /opt/zimbra/data/ldap/config -b "" -q -l /tmp/ldap.bak
_#################### 100.00% eta none elapsed none fast!

When I tried to restart zimbra service using zmcontrol I get error message like this:
[zimbra@mail2 ~]$ zmcontrol status
Unable to determine enabled services from ldap.
Enabled services read from cache. Service list may be inaccurate.
Host mail2.mycompany.com
Starting logger...Failed.
Starting logswatch...ERROR: service.FAILURE (system failure: unable to lookup server by name: mail2.mycompany.com message: [LDAP: error code 49 - Invalid Credentials]) (cause: javax.naming.AuthenticationException [LDAP: error code 49 - Invalid Credentials])
zimbra logger service is not enabled! failed.

this is fixed with I change hostname on mail2.mycompany.com to mail.mycompany.com, after that I've tried to restart zimbra service's and like look good, all services is running and two separate hostname on my make me confused, and I tried to restart zimbra services and my zimbra services couldn't running...

Next step I tried login into administration backend and getting problem to, on my server status i got a two hostname here, please see attaced files......

Sorry for my english....
