Upgrade FileMaker Server from v18 to v19

[fishtech]

Hi,

I am running FileMaker Server 18.0.4 (macOS 10.15.7) with MirrorSync v6.21 (the latest at time of posting).

I would like to upgrade to FileMaker Server 19 on macOS 12 Monterey.

Is there a way that I can upgrade the server and keep MirrorSync intact? I'd like to avoid the remote users needing to sync in advance, then needing to download new files after the upgrade if possible.

Many thanks,

ft.
