Installing old release of LoRa Server + App Server

I Want to install LoRa server on most recent release of Version 1.x
According to quick install would it be just necessary to replace ‘2.x’ to ‘1.X’ in the repository step? The Key is the same?

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1CE2AFD36DBCCA00

Add the repository to the repository list by creating a new file:

sudo echo "deb https://artifacts.loraserver.io/packages/1.x/deb stable main" | sudo tee /etc/apt/sources.list.d/loraserver.list

Yes, that is correct. By using the 1.x repository, you will get the latest 1.x version of LoRa (App) Server.
