Hello,
I’m using RocketChat from bundle package. I would like to migrate it to snap package, how can I do it without losing any data?

Typically people actually go the opposite direction and move out of snap because they out grow it.
If you have a small server snap is still of course a good choice.
Moving from bundle to snap would go something like this:
```auto
mongodump --db rocketchat -o dump
tar -zcvf backup.tar.gz dump
```
Of course sub rocketchat with the name you used for your database.
Move the backup.tar.gz to the server running the snap.
Then the snap restore steps listed here: [https://rocket.chat/docs/installation/manual-installation/ubuntu/snaps/#how-do-i-restore-backup-data-to-my-snap](https://rocket.chat/docs/installation/manual-installation/ubuntu/snaps/#how-do-i-restore-backup-data-to-my-snap)

That’s exactly what i tried to do and it did not work. My backup is 500Mo is it because it’s too big? I get an error while the script succeeds to export the tarball… what’s wrong?

True. Snap is hard coded to expect the database (directory) to be named `parties`😶

@sing.li
So i tried it. Indeed it caused that simple error.
When i import i have an error in mongorestore.log though ☹

hmmm… seems you’re running 32 bit mongo server … the limit is 2GB on 32 bit mongo. Your DB size is 500MB uncompressed, right?

Uncompressed my database is 597 MB
I tried to redo the whole snap install after updating everything and starting from a clean slate.
Now it seems the import goes well until one database file: (see the log file here [https://pastebin.com/x8c6Vzm4](https://pastebin.com/x8c6Vzm4))
The error at the last line is the following
```auto
assertion: 15936 Creating collection parties.rocketchat_raw_imports failed. Errmsg: exception: can't map file memory - mongo requires 64 bit build for larger datasets
```
Still the same actually but not happening at the start this time… weird. The raw imports is a tiny document actually. And it seems there is no error when mongo tries to import the 522MB chunks.json file

Here is a historical note from official Mongo FWIW
[https://jira.mongodb.org/browse/SERVER-1811](https://jira.mongodb.org/browse/SERVER-1811)
1. ARMHF is not officially supported
2. Even for supported arm64 platforms, only WiredTiger engine is supported - they seem to have problem getting the mmapv1 engine to work with full spec.

I don’t understand… The snap install works because i managed to install it. So why is it impossible to restore a backup? Does this mean the provided path to install RC on Raspberries can’t allow database restore nor migration? I’m confused. How can it work and not work at the same time…

Hi again!
I’ve experimented some things for quite a few hours.
I’ve had success in importing a database (without the dispensable uploads file) thus making the total gzipped database a size of 18Mo. When importing no errors this time ! 😄🥳
The thing is the **three services are active** but the URL returns a 502 error.
I think the Caddy log is the relevant one

Looks like rocket.chat didn’t come up, probably due to different versions between your current snap install and the one you had before?

It was indeed the case. My RocketChat installation was at the last version. Snap install is not fully up to date.
Does that mean i will only be able to migrate when the snap install is up to date?
