Migrating My Sites to new dedicated site host

Question

We have taken over a site where My Sites are placed in the Intranet web application.

I want to migrate the My Sites to a dedicated host site.

From what i have been able to find out so far, I will need to do an STSADM -o backup of each personal site and restore it into the new content database.

I will be automating this process using PowerShell.

Has anyone tried this?

Any caveats i need to be aware of?

Since i need to move site collections out of an existing content database into another, as far as i can see i cannot use a simple SSP migration.

Any help appreciated :-)

EDIT: I wrote a blog post on how I solved this using stsadm mergecontentdbs here

Answer 1

Have you considered using stsadm -o mergecontentdbs to move them all into a single content database and then attaching that content database to the new site host? I don't know for certain that this will work, but it seems like it would make the process much simpler and with less risk of data loss as the sites will still be available.
