So I created a backup on iOS TF4 and copied it to my Mac and imported it there on TF5.
I compacted the database and renamed it and copied it to the desktop.
Then I conecten first my 2 iPads and then my iPhone and copied the database to them. I had to close down the TF5 on the iOS devices to be able to see the copied file.
Then I started up the IBM sync and now Im up running 4 hours lately.
This is not an optimal situation and as I said earlier, I’m worried how this will be revived. Lets hope for the best.
There are also confusing double possibilities in all the versions which make it all verse.
But now it looks fine :-)
