Migrating servers

[safwanadnan]

I am running my waha inatance on a cps but i want to chsnge my providers. I store session data and was wondering if i copy that previous folder and mount it while starting the docker instance on the new vps, will i get all the session and its data to the new vps and will it stay logged in? Can I perform this migration without any interruptions?

This is a very good and important question. More or less, this situation will come up for the majority, and it would be great if a complete guide or documentation were prepared for the steps that need to be taken to address this.

Hi!

There are two cases:

1. You're using Local file storage (aka -v .sessions:/app/.sessions in docker run command or volumes) in docker compose
2. You're using PostgreSQL/MongoDB

For 2nd one you just stop the current container and run it on another server (if it's external database server)

For 1nd case you need to:

1. Stop container
2. Copy .sessions folder to the new server
3. Start a container on new server

Can I perform this migration without any interruptions?

No, WhatsApp doesn't allow connecting from multiple places.
If you're using NOWEB/GOWS engines - you'll get messages when you back online (not in case of WEBJS, if I remember it right)

I am using the NOWEB engine and file storage and I thought the same, to use the .session file and copy it to the new vps. My question still stands, I can take a little downtime while the session storage gets copied to the new server and the docker instance gets running. However, I still need to know if I stop the old vps before getting the other one up and running will my sessions persist or will they have to be logged in again?

If you stop sessions before, then copy, then run a new one and properly configure it (using the copied folder) - it should be good.
It can unauthenticated a little of sessions (like 10 out of 100), but usually it goes good!
From WAHA point of view it's almost like the container restart, so should be good
