I am using CL 6.00 with Ms Outlook , Android and synchronizing via DejaCloud. My OS is Windows 7.
I am intending to reinstall Windows 7 on my PC.

What will happen with the synchronization between Ms Outlook and Android? (Of course, I will use the same Outlook.pst file )
Do I have to wipe all records on DejaCloud before the first synchronization?
And do I have to wipe all records on Android before the first synchronization?

I am afraid avoiding to wipe all records will result in many duplicate records.

Thank you for your help.
