Thanks chewitt
One detail I did not tell about : as I am setting up a new PC (hardware and software), I also decided to rationalize the hard drives organisation. So I'll redefine my sources from scratch and not use the old sources.xml file.
So, to be sure :
00 - backup advancedsettings.xml and a few addon settings from userdata (Remote addon typically) from Libreelec 8
0- update MariaDB (and possibly DSM too) on Synology
So I'll define brand new sources directly from Kodi on the fresh install.
It's a bit more complicated than copy/pasting from old install to new install, but the steps you describe are the same right ?
1 - clean install on one device
2- define paths/Media types on Kodi's interface form that device --> generate new sources.xml
3- check SMB access
4- paste advancedsettings.xml on the migrated device
5- restart Kodi and launch the DB migration
I'd also SSH in to tail the kodi.log file to check for errors during the DB migration as it will need to step through quite a few versions and will take time.
Can you explain that ? I did not understand.What do you mean by "SSH in to tail the kodi.log file" ?
Many thanks
