When is Migration necessary?

Hi, I have a self hosted instance running on version 1.4.2. I want to upgrade to the latest version. In the 1.4.2 changelog it was mentioned to run the migrate command but after that i can't see a mention of it anywhere else.
As a suggestion, it would be better if the upgrade command took care of migration when needed as well.

Generally migration is required when upgrading to a minor version such as 1.3.8 to 1.4.x . I think there were some internal changes that required migration from 1.40 to 1.4.2. You can upgrade to the latest patch without migration since it's still 1.4.x

i've seen in #channel someone mentioning a migration is necesary in between, doesn't remember where, so just wanted to ask the staff.

You can run migration if you want to be really sure, though I don't think it's necessary

There's not issue in running it if it's not needed?

Yes

However, it's important to backup just in case

If changelogs dont explicitly say run migration then dont.

Ensure you backup, upgrade and check if everything works. If so, dont run migration, if something seems off, run it.

I upgraded from 1.4.5 to 1.4.13 and ran migration n my functions stopped executing. Not saying migration had anything to do with it but thats what happened. I am currently in the process of migrating data to a new server so be careful and can't stress this enough, take a back up

I do have an automatic backup system setup since one update broke everything even in production.

It just doesn't give me the confidence to use appwrite when even upgrading can cause downtime. Taking backup and restoring when things go wrong is just too much downtime

I use to avoid that a parallel instance

First I migrate to the temp parallel instance, then I switch there and after upgrading everything I switch back to the original instance

I know it's not the best approach but 🤷‍♂️

that is still downtime

When you migrate using migrations feature there's not any downtime

Well, if you have lots of requests then yes, there's a small downtime between switches

But sincerely, I don't think that's bad at all. You can do it in less active hours. In my case I have 99.98% uptime

Since you mentioned migration, can you take a look
