BW 7.0 to 7.3 upgrade-Post upgrade activity and Transport the changes

Hi Experts,

We have upgraded our BW system from Release 7.0 to 7.3. As part of Security post upgrade activity I ran Migration steps,

RSECADMIN-Extras->Migrations->Migration:Release 7.0 to Release 7.3. and later SU25 steps too.

I fixed the Roles appeared in SU25 Step 2C and made below Characteristics as auth relevant,

0TCAACTVT

0TCAIPROV

0TCAVALID

But I have few doubts before Quality movement,

1) Do I need to Run the Migration steps again in Quality and Production?

RSECADMIN-Extras->Migrations->Migration:Release 7.0 to Release 7.3

2) Do I need to transport only above Characteristics to Quality and Production or need to transport all the Characteristics and Analysis Authorization?

3) How to transport Characteristics?

Please provide your views.

Regards
