[Deploying Sakai] Migrating from database storage to filesystem storage

Hello All,

Our Sakai installation stores binary content in the DB (approx 180GB now)
We've decided to migrate to FS storage.

I just want to make sure that the process I'm intending to go with is right:

1) Shut down tomcat
2) Add those 2 lines to sakai.properties:

bodyPath at org.sakaiproject.content.api.ContentHostingService=/path_to_nfs_share_mount/
convertToFile at org.sakaiproject.content.api.ContentHostingService=true

3) Start up the Tomcat

Now the questions:

How can I make sure that conversion process is finished?
Should I remove
"convertToFile at org.sakaiproject.content.api.ContentHostingService=true"
from sakai.properties after conversion is finished and restart Tomcat?

Any problems with 2 or more sakai nodes accessing this share at the
same time (currently we have 2 Sakai servers working on the same DB in
HA mode)?
What could be approx. conversion time for 180GB DB?

Anything else I'm missing and can be useful?

Best Regards,
