Hi @itinfrastructure_7135 ,
The easiest approach is this:
Notify users of downtime
Shutdown old server
Migrate database, files
Start the new server
Edit DNS to the new server
Using the drop-path isn't required, and that whole process probably wouldn't take too long.
There are ways to reduce downtime, but that mostly involves using something like "robocopy" or another tool to mirror the package files across servers. The database is relatively small to backup/restore.
Otherwise it sounds like you're on the right track!
Cheers,
Alana
