Is it possible to run R80.10 migration tools in Management server running on R77.20 SPLAT and collect a database backup ?
Yep, make sure to use the latest version of march 2018 of the migration tools. See SK111841
You can use the Checkpoint Upgrade Wizard (http://supportcenter.checkpoint.com > Upgrade/Download Wizard ) and follow the correct procedure to upgrade and when you are upgrading choose the R80 migration tools according to your current OS (Gaia/Splat). When I did a migration from R77.10 to R80.10 I had to choose Migrate tools R80.10 for splat because even though the OS is Gaia (R77.10)I had to download splat R80.10 migration tools. This was confirmed by a TAC Engineer for me.
