File transfer issue?

Recently we deployed 2.6.3 version of spark via GPO in our environment… the problem is we still have client on regional sites who were using the lower version 2.5.8 (not domain member)… now they cannot transfer files with different client version… is there any other way resolving this issue without upgrading other clients??..

Any ideas or suggestion on how to resolve this issue??

Nothing really can be done unless upgrading those 2.5.8 clients to 2.6.3. Though i can’t say this will 100% fix the problem, but that’s the only way. Or downgrading your clients to 2.5.8, of course.
