One more

what is different between NBU 6.5.X and NBU 7.5.X in Architech level ( not advantage or feature between these two)

1) Answer is no.
You need 2 different installations to manage the different versions.
What I do is to create installation folders up-front: NBU65 and NBU75.
Install and patch each version seperately.

2) I am not aware of any such documentation.

I don't know about hard limit, but Backup Planning and Performance Tuning Guide provides guidelines for capacity planning - for example, catalog should not exceed 750GB, and total number of catalog entries should not exceed 2,000,000. Number of client is not limited, but number of jobs per 12-hours on a single master server should not exceed 20,000.

Not sure what you are expecting w.r.t. NBU 6.5 and 7.5 differences... 

Basic Archtecture is the same, except for Image headers that are moved into EMM database in 7.5.
Other changes introduced in  7.0 and 7.1 are obviously incorporated in 7.5 as well - such as NBAZDB database introduced in 7.1 (See 7.1 Release Note). Audit trails were introduced in 7.0.1 and expanded in 7.1. Changes to VM backups in 7.1.
Deduplication introduced in 7.0.

See 7.5 Release Notes:

Decide for yourself which ones are Architecture changes and which ones are features.
