How to upgrade pgAdmin4

Hi thank-you for maintaining this wonderful program!

I have pgAdmin 4 on Windows 10 installed - version 2.1

I would like to keep current versions but had so much trouble connecting to my postgres database, I am apprehensive.

My postgres is on my remote Linux server and goes through SSL with certificate keys.

I am not much good with Linux and it took a long time to get up and running.

So here are my questions:

    1) Are there any specific types of backups I can/should perform before upgrading to pgAdmin 4 version 4.6

    2) Am I correct to assume I just run the downloaded .exe file to upgrade?  What is the .exe.asc file used for?

            here are the files I found on the website:

I appreciate your time!
