We are usning zcs - 4.5.10 on RHEL 5 - 64 bit in production environment. And one domain is running on this server without any issue.

Now we got another client and currently their around 100 accounts are running on exchange server. And now they want to migrate their domain and mail server to zimbra.

I searched on net and found there are below 2 ways by which we do this migration :

1. Use the zimbra Migration wizard.
2. To export the contents of the MS Exchange folders to a .pst file and import them using the Zimbra PST Import Wizard.

and i got little description for both menthods but i couldnt find out proper procedure for this task.
So is there any link from where i can get detail precedure for migration ?

And one more question, duringh migration , will it affect my existing domain ???
