Migrate/Upgrade CA from windows 2003 to windows 2008/R2

Migrate/Upgrade CA from windows 2003 to windows 2008/R2

I came across various forums people need to migrate CA from old server to windows 2008 or 2008 R2, since business is taking switch from 2003 to 2008 because of the benefits from the windows 2003 to 2008/R2.

I have seen various FAQ’s like:

1.Can i migrate to another server with different Hostname?

As long as windows is running on windows 2008 or 2008 R2.

2. Can i change the CA name while migration?

No, if you do that, you are going to break the CA trusted chain & you have to start from fresh.

3. Shall i first install CA on windows 2008/R2 server or uninstall first on windows 2003 after taking backup.

You need to take the backup first, uninstall the CA on old server(else there will be conflict) & once its been uninstalled, rename the old server or remove it permanently & give time for changes to replicate in domain, once replication is complete, install the CA on windows 2008/R2.

    Came across many articles which says Hostname change of destination server is supported , but the CA name must stay the same.
    What is the best practice to avoid any issue while moving CA from 2003 Server to 2008 R2 ?
    Do we need same Hostname ?
