I'm long K9 user, and I was aware of it becoming Thunderbird, but I need to clarify what should I do to easy eventual transition, hopefully without having the deal with all my K9 settings...
Today K9 turned into Thunderbird Beta for Testers, however there's already an app called that way Thunderbird Beta for Testers showing up on f-droid. Thoug the actual ID of each differ (com.fsck.k9 vs. net.thunderbird.android.beta).
What should K9 users do, to avoid losing its current settings (accounts, folder settings, encryption and so on)? Should we remain using the K9 app, and hope that when it goes away then the thunderbird app replaces it somehow automatically and pick all accounts and settings? Should this period when the two apps with the same name coexist be used to install thunderbird beta for testers, hope that it pick all settings from K9 up, and then remove K9?
It's somehow confusing, I was originally hoping at some point K9 just turned into thunderbird, but at once, automatically, without still having two apps, so I'm wondering what's next. For now I'm just still using the K9 app with thunderbird name...
Thanks !
Edit 1: Many thanks for those who replied, at least I don't have a google account, and no need to inherit the OAuth to google, or any other of such account for that matter, although I could remain to K9 I migrated to Thunderbird official release (no beta) without issues. It sounds like a good opportunity to migrate to Thunderbird.
Edit 2: It's sad that the OAuth can not be inherited, though understandable. For those who were just using TB or K9 for a long time with gmail, and the account gets into the infinite dependency loop of requiring a device already logged in, given the stupid security question has no answer, then perhaps it's time to ditch google and look for an alternative, I haven't found anything useful to help around there. Google actually sent a message indicated it has protected the user from herself, and inhibited her attempt to reach her own account. Meanwhile, just staying with K9 seems OK, since it's still there (just a metadata name corrupted but the app ID remained K9 still).
I had net.thunderbird.android.beta already installed from the official github releases, so ig that's the official variant. I just wonder if it can automatically update from F-Droid (basic), considering it was technically installed by my browser.
It's easy to find out. Navigate to Thunderbird Beta in F-Droid Basic and look at Versions. If you only have a single version there, then you have to delete it. If it says that no version with a compatible signature was found, so too. If you have three versions to choose from and one of them is installed, then you don't need to do anything, because then you will get updates.
Looks right. Then you don't have to do anything. I mean, it's up to you, but do you really want to continue using the beta?
I use betas almost everywhere, and apart from firefox sometimes having minor bugs (expectable in nightly), I've never had any real issues. So yeah, until it breaks down completely I'll just use beta.
