Hi Vinod

I've opened up a ticket for you in order to get you a solid answer. I'll post this response back here for the rest of the community once we get you an answer.

Thanks

Andy

Hi Vinod,

Although a migration to a 9.0 Satellite is strongly recommended, a 7.8 Classic Proxy Server should be backwards compatible. However, some minor tweaking might be necessary. The instructions can be found in the Classic to Core migration guide.

Thanks,

Ana
