I have a large project, and decided to see how it will run in 2019.3. I've opened the project and it asked if I wanted to convert the project to use the new Asset Database V2, so I said yes. Is this process very slow for everyone? Because this conversion process has been running for 2 full days so far, and I have no idea how far along it is. What seems to be taking most of the time is the processing of .fbx models. Each one of these seems to take 30 seconds, or a minute (or possibly longer, I haven't times it), and I have many thousands of .fbx files in my project. I guess I'll let it keep running, and see what happens, but I've never seen this kind of thing when using new versions of Unity. In the past,a full re-import has taken (if I remember correctly) between 1 and 3 hours.My guess is that converting to the Asset Database V2 is just something that can take awhile to complete, but perhaps the process isn't optimized.
