Thanks, Mike. I think that may be the next step - to take the LTM out of the picture to see if we have any issues sending data directly to one of the CAS servers.

 

The migration batch shows that it has transferred gigs and gigs of data, however we open one of the user reports to get additional detail it shows that zero messages have been transferred.

 

I understand that the rates get throttled by Microsoft, however I think we should see better than 20MB / hour.

    Out of curiosity, did you ever go directly to the CAS server and see a change? We're experiencing a similar issue.

    I believe so and I don't think we saw any change. We determined that we could only do so many migrations at once before it causing all of the migrations at that time to halt. Once that happened, we had to cancel all migrations and start again - which eventually found that we couldn't do more than like 5 or 6 at a time to be reliable.
