I think this is a really good suggestion. It would take a lot of pressure off the migration process. The only potential downside is that copying into blank issues might be slower than just moving the issues. I have not tested this, so I don't know yet, but even if copying is slower it doesn't really matter that much if there is nothing (e.g. re-enabling repo access) that is waiting on the process to complete. -Tom > On Wed, Apr 29, 2020 at 8:25 AM Tom Stellard via cfe-dev > <cfe-...@lists.llvm.org <mailto:cfe-...@lists.llvm.org>> wrote: > > Hi, > > Thanks to everyone who provided feedback.
