If we use this approach I would like to do it slightly differently.  

1. Put the 4GB and 2GB disk on opus, bring it up as new-*rosebud*
2. Migrate ronald-ann data to new-*rosebud*
3. Remove ronald-ann from server CellServDBs, take it down.
4. Bring up ronald-ann as new-*ronald-ann*
5. Migrate rosebud data to new-*ronald-ann* (leaving behind vlserver).
...


This has the advantage that Ronald-ann gets to stay ronald-ann.  There
are some paperwork advantages to this if nothing else.

When will opus be ready to be re-installed?
