32bit to 64bit on CentOS 5.3

[jpbuse]

Making the move from 32bit to 64bit. Both machines are running CentOS 5.3 if that makes any difference. I've read over the guide at Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki but I noticed the version is 4.3.x. Does this guide still apply for say 5.0.15? I had followed Moving ZCS to Another Server » Zimbra :: Blog when moving from one 32bit machine to another 32bit machine and it worked perfectly.

Can I simply install 5.0.15 NE on the 64bit box w/ the -s flag, sync over the data from the 32bit machine, change IPs and be done with it?

No you can because OpenLDAP database have a different format between 32 and 64 bits.

There are several threads on the forum with additional explanations of "how to do such migration".
