Workspace Migration

System

Hi all, I would need some help with the following matter:

I have to move some workspaces from one library to other, and I know it is not as easy as it sounds. I know that Interwoven will release a tool called "Workspace archiving" to do this, but unfortunately it will be able in 8.2 version, and I have to migrate the workspaces in 8.1 version.

Has anybody done something similar? Could anybody recommend me the steps to follow to success this migration?

I would thank any information related with this.
