I have put in an enhancement request for a proper server move routine for Opera 3 SE. Currently the advise is to install on new server set up all the users and companies and then restore the data from an Opera backup.
But I have a couple of SE sites that have a lot of users and one that has set permissions down to what can be seen on the action buttons they really wouldn't want to set up all their users from scratch.
Also any payroll sites will lose the ability to resend historical payslips and P60s as this is held in the Core database which we can't restore.
Please vote so they look at this properly.
