Can we drop a 7.6 MaxDB into a 7.9 MaxDB?

Hi,

I've got to migrate a 6.3 Content Server (based on 7.6 MaxDB) on Windows 2003 (which according to the PAM isn't supported but has been working ok). Into a 7.9 MaxDB on Windows 2012 R2. We might have to go to 2008 first, then 2012

There is very little info out there on whether The Content Server 6.3 currently (6.4 maintenance will soon end) will be supported on 2008, but I'm not sure that this will matter as long as the MaxDB side is correct.

I've read somewhere that from 7.5 you can drop a any version into 7.9? - is this true?...could someone help out on a possible upgrade path, strategy?

Regards

Neil
