We have a test tenant with 9 videos in Office Video. We tested out the migration to stream today. After about 3 hours, the migration failed with "your migration to Microsoft Stream is blocked. Open a support ticket." To open a support ticket, it's a bunch of hassle for us - we have to contact a third party, get permission, etc. We are testing as we're getting ready to do the same in our production tenant. It has a lot more videos. When you look at the videos in Office Video, there are video views that are associated with them. Can you help?
I looked at the issues in Excel and it is as follows:
I'm in the same boat... Despite sending clear screenshot attachments to support, the call back only consisted of asking me to try it on different browsers, asking if the PC was rebooted (took 2 days for a call back, so it was), and if it was tried on a different network. The second callback attempted to do the same process, claiming the ticket wasn't updated from the original call, and that they'll escalate it. Hopefully someone will have an answer soon.
