Upgrading hard to reach SEP clients

Hi,

We're a large site and have successfully upgraded 99.9% of our workstations to SEPv14 but still have 40 or so laptops on SEPv12. They are all remote and only come on line intermittently on the VPN when they will check into the old SEPM. We’re struggling to update these with our usual methods.  We’re now wondering if there's some way we can set the old SEPM to install the new SEPM client? Or, set it to move them over to the new SEPM for management when they check in??.

In the meantime I've set Live Update Policy on the old SEPM so clients go direct to Symantec for defs if we can't move them over. Is there more we should be doing for any clients that get left behind?

Appreciate any help.

Thanks
