Hello.
I have RocketChat 2.4.6 and I need to scale it to a 4.x version to make use of new features.
But I can’t use the instance that is in use by the company.
So… how can I install version 2.4.6? I couldn’t find any documentation that could help me and I don’t know if it’s possible to follow the current version’s documentation for installing the old version; the attempts I’ve made follow the requirements on the version release page on GitHub (Release 2.4.6 · RocketChat/Rocket.Chat · GitHub).
Can anyone help me?
Thanks 
Hi! Welcome to our forums
We have all older versions in our docker (our suggested deployment method) repo:
https://hub.docker.com/r/rocketchat/rocket.chat/tags?page=1&name=2.4.6
You can also use our own docker repo, for instance:
registry.rocket.chat/rocketchat/rocket.chat:2.4.6
Now you can dump your production data, restore in a 2.4.6 staging deployment and start your tests into upgrading to 4.6.3, our latest released version now.

Friend, your answer helped me a lot.
I’m gradually making the updates in the test phase and so far everything has been working very well.
Thank you very much!
