VMM 2016 - WSUS and Library OS version support

We currently have a VMM 2016 server running Server 2016.  We also have a Server 2012 R2 VMM Library server and WSUS server.  I'd like to upgrade to VMM 2019.  I know VMM 2019 doesn't support Server 2012 R2 hosts, library or WSUS servers.  I'd like to get to Server 2019 for everything, but VMM 2016 doesn't support it yet for hosts, library or WSUS servers.  What's the ideal upgrade process considering I'd like to get my VMM server, Library Server and WSUS server all up to Server 2019?  I see it as one of these two options:

1. in place upgrade of library and wsus servers from server 2012 r2 to server 2016
2. Uninstall VMM 2016
   
3. in place upgrade of VMM server to Server 2019
4. install vmm 2019
5. in place upgrade of library and wsus servers from server 2016 to server 2019

This is a lot of Server OS in place upgrades, which isn't generally a path you want to take for servers.

Option #2

1. provision new Server 2016 library and wsus servers and add them to VMM 2016
2. uninstall vmm 2016
3. in place upgrade of VMM server to Server 2019 (or provision a new server 2019 with the same hostname and IP of original vmm server)
   
4. install vmm 2019
5. in place upgrade of library and wsus servers from server 2016 to server 2019 (or provision new Server 2019 library and wsus servers)

I'll probably go with option #2, but am I missing anything?  Can anyone fill in any holes or anything i'm not thinking of? 

Thanks!
