Content server upgrade from 6.40 to 6.50

Hello,

As content server version 6.40 is not supported by SAP now so we need to upgrade it to 6.50. Can anyone share the knowledge who performed it?

I have gone through note 514500 and understood that patching is as simple as replacing some old files under particular folder with newer version files (v6.50). However, I wanted to get confirmation that upgrade is also same as patching or not?

Is there any dependency of content server 6.50 on MaxDB version which will be our database?

Regards,

NK
