Admin / Designer

I am currently using 6.0.2CF1 on my client/admin/designer. (Admin cum Developer)

Will the new 6.5 client/admin/designer have any issues on my current development and administration work? Your feedback is appreciated.

Servers that I admin and design to with NO problems using 6.0.2CF1 are a mixed of:

5.0.11,

5.0.12,

6.0.2CF1,

6.0.2CF2
