It's easy if you don't share passwords with others. I have my whole family and business using it, and there's lots of shared folders.

Convincing my wife and colleagues to all switch simultaneously isn't feasible unless this data fiasco gets worse.

It'll only going to get worse. Better move now before it's too late.

I tried migrating from LP to BW and got import errors. Bitwarden's error message was very vague (along the lines of "sorry, something went wrong") and I haven't been able to track down what entries were causing the issue. I've tried 3 or 4 times including trying to reproduce with subsets of the full collection but it's too much of a pain with hundreds of accounts and I so far haven't been motivated enough to manually transfer them or to write a selenium script to do it automatically.

Moving to vaultwarden (the open bitwarden server implementation) was also really easy. Just installed the package in Arch, setup the vhost in nginx, put the vhost into my local DNS and slightly adjusted the vaultwarden config file. Now I use bitwarden clients everywhere and point them to my server.

Since I don't feel 100% comfortable having my self hosted things on a public IP, I put it only on my LAN. For remote access (e.g. phone) I use wireguard.

Just check your data after re-importing the passwords. LastPass sometimes has issues with the export (see elsewhere in this thread) and does not export attachments at all. You have to move attachments manually.

You can't export all the passwords, some extra fields are not exported by LastPass, so there is your PITA when some site asks a security question you had an answer to in that unexported field
