Database mirroring endpoints - difference between 5022 and 7022

Question

I'm prepping to install SQL Server 2019 Always On availability group cluster. Part of the install is to specify database mirroring endpoints for each SQL instance. In the past, I used ports 5022, 5023, 5024, etc, for the endpoints for multiple instances. I saw a recent MS article with an example that uses 7022 for the endpoint. When I look up the TCP port descriptions, I see:

5022 = "MSSQL Server Replication and Database mirroring endpoints"

7022 = "Database mirroring endpoints".

What's the difference? Does it matter which port(s) I use?

Thanks.

No, you can use any port, as long as that port is not use by any other program in the machine. The only purpose these "official" port designation serves is exactly to avoid such collisions.
