@Chris Deal Thanks for reaching out to Q&A. I understand you are moving to Azure Cloud based PM software and want to know which ports need to be opened.
Can you explain how you are planning to setup your software so I can assist better? If you have a network diagram of your plan, please provide it.
Will you be hosting this software on a server, will you be using any Load balancing, firewalls in front of it? Please explain more details.
If its a simple setup with the software on a server, then you would open relevant ports that the software would use on the Network Security Group of the server. Thank you!
