Merging events from aw-server DB into aw-server-rust

When I first installed ActivityWatch on this system (Mac 12.6.7), I accidentally left out the configuration file editing to set aw-server-rust on startup, so I have a weird mix of time recorded across two different DBs (since it would start the wrong server on infrequent reboots, then usually I would catch this at some point and switch them using the menu bar icon). This shows up in different totals across the same interval, neither of which has enough time to cover everything. Now that I’ve figured out the problem, how can I pull everything into the same database?
