SAP Content Server Upgrade from 6.3 to 6.4 & MaxDB 7.3 to 7.8

Dear Experts,

We are in planning of upgrade SAP Content server from 6.3 to 6.4 and MaxDB from 7.3 build 35 to 7.8.

For Content server upgrade is that we need to install the Content server 6.4 and install the latest MaxDB 7.8 and export and import the data.

We are on Win 2003 32 Bit and we are migrating to win 2008 R2 64 Bit.

Is it possible directly using database copy and restoring in MaxDB 7.8 version?

Or we need to use loadercli for migrating the data.

As per the SDN Link http://forums.sdn.sap.com/thread.jspa?threadID=1649661

for content server upgrade is by replacing latest dll files at the respective dir.

Pls let me know your views and known issues.

Thank You,

Mahesh
