We have a setup consisting of 4 virtual machines: Domain controller, database server, application server and terminal server.
These are VMs that are hosted at Azure. We cannot upgrade the operating system in a traditional way (in-place upgrade), but have to rebuild the VMs and transfer the services and data. We have already replaced the domain controller with a Windows Server 2019 (previously: 2016). This worked as expected without problems.
Now we have to upgrade the application server to Windows Server 2019. The VM with Windows Server 2016 must also be replaced by a new one with Windows Server 2019. GS 2020 CU02 is installed on the application server. The database server is - as mentioned above - separated.
Is it possible that I set up a new Windows Server 2019 VM, stop all services on the existing GroupShare server and shut it down (hoping I will never have to start it again) and then install GS 2020 CU02 on the Windows Server 2019 and simply enter the access data of the old server as database server?
Maybe it is important to mention that the host name of the application server has to change for technical and regulatory reasons. I cannot avoid this. However, the host name of the database server and the name of the database instance would remain identical.
Has anyone already had to do anything similar?
