Parameter sets lost after upgrade to V20...

After migration to V20 all parameters were gone. I did not export the databases before the upgrade. Is there any way to retreive the (old) databases that were existing in V17? Where are these databeses located?

You could export and then import them. - Exporting and importing parameter sets: https://support.industry.siemens.com/cs/ww/en/view/109828368/168793877259

So you would have to export the parametersets in Runitme of the V17 system. If you have a panel or PC RT it is saved in and SQLite database files by default on the device itselfe. to get it into annother or a new system you have to export and then import it (but all in Runtime) Bye Murof
