Unable to upgrade from Postal v1.x to v2

[japps20]

Hi there,

I currently have Postal 1.x and following the instruction here (https://docs.postalserver.io/getting-started/upgrade-to-v2) to update to Postal v2, but it just went straight to v3 thus breaking a few things.

Please is there a specific way to upgrade specifically to Postal v2 and then v3?

Todo: presumably there is a way of cheating and cloning the install repo for v2 specifically and not v3?

I am not very technical but I was looking at https://github.com/postalserver/install/blob/main/bin/postal and I can see

FORCE_VERSION=""

Does that mean it may be possible to specify the version? If so, how will the version be passed to the install command?
