We want the whole server reformatted so what is currently there is irrelevant.
No need to try to salvage any data.

We switched over mail and lists on that server already to osgeo9 over the weekend.
We plan to keep osgeo6 live for perhaps another week or so and then have you shut it off.

We have a backup of all the pieces we cared to keep already.

Right now we are just trying to figure out how much we want to spend for disks on this server
Vs. how much space we'll be able to expand.
