Upgrade Lotus Notes 4.6 to 5 and synchronisation

[Erik]

Recently I was forced to upgrade from LN4.6 to LN5. LN5 was installed on a new harddisk, then I installed PsiWin2.3.3 and upgraded for the use with LN5.
Now my synchronisation from LN5 to Revo works fine, but when I need to write the other way around, I get a message "Unable to update database, invalid or non existent document".

I checked all paths in the settings, which are correct now.

FYI, I had LN4.6 on a Windows 2000 machine, my current LN5 is on an XP machine.

Should I maybe run PsiWin setup as a Windows 2000 program?

Solved the issue myselve. Apparently, the upgrade to InsyncPro (e) does not change the synchronisation "protocol". You have to force a new synchronisation, defining version 5.0.
From then it runs smoothly.
Agenda/To Do/Anniversaries work as well as Contacts. Events in the agenda still cause problems, but I guess this is trial and error.

Anyone knows how to get rid of double entries (approx. 500) without doing this manually??
