Possibility change from 32bit to 64bit?

[p_nyet]

Dear All,
Now I've already running zimbra 6.0.1 under CentOS 5.3 32bit...
And I thinking about upgrading memory and replace my OS version with a 64bit
Anyone know about procedure to move zimbra 32bit to 64bit?

Please advise....

Thank's Bill,

I've already follow the instructions from zimbrablog about exporting ldap accounts, and finished up without problem. But when I tried to start zimbra service or see service's status I get some error messages.

This is instructions:

Zimbra’s LDAP Wiki Page: LDAP - Zimbra :: Wiki

UPDATE for 6.0:

To dump on the 32-bit:
/opt/zimbra/libexec/zmslapcat /backup
Which is essentially running ${zimbra_home}/openldap/sbin/slapcat -F ${zimbra_home}/data/ldap/config -b “” -l $DEST/ldap.bak.${D}

To import on the 64-bit:

1. rm -rf /opt/zimbra/data/ldap/hdb/*
2. If this is an ldap master with replicas: rm -rf /opt/zimbra/data/ldap/accesslog/*
3. mkdir -p /opt/zimbra/data/ldap/hdb/db /opt/zimbra/data/ldap/hdb/logs
4. If this is an ldap master with replicas: mkdir -p /opt/zimbra/data/ldap/accesslog/db /opt/zimbra/data/accesslog/logs
5. Copy the file /opt/zimbra/data/ldap/hdb/db/DB_CONFIG from the 32-bit server to /opt/zimbra/data/ldap/hdb/db on the 64-bit server. Note: If this file does not exist, or is empty, creating it may improve performance.
6. Type chown -R zimbra:zimbra /opt/zimbra/data/ldap
7. Copy from the 32-bit server to the 64-bit server the /backup/ldap.bak file.
8. Type /opt/zimbra/openldap/sbin/slapadd -q -b “” -F /opt/zimbra/data/ldap/config -cv -l /backup/ldap.bak.

And this is error messages when I tried to start zimbra service's

[zimbra@mail ~]$ zmcontrol start
Host mail.lerindro.com
Starting ldap...Done.
Failed.
Failed to start slapd. Attempting debug start to determine error.
backend_startup_one (type=hdb, suffix=""): bi_db_open failed! (-1)

I think the problem with ldap password or some parameters (suffix) but i don't know how fixed the problem..

Confused...
