Are you migrating to a new server? Just delete Synqup on the old server and make a new installation on the new server.
Deletion can be done via a UNIX000.EXE in the installation folder located by default in C:\Program Files (X86)\Synqup.
The location where invoices will land on the new server remains unchanged. For example, if you are using a UNC path and the delivery path of invoices changes, please contact firstname.lastname@example.org in due time.
