Thanks Guys!!!,
It's good to know ASM upgrade should be an "LTM-like" procedure. The configuration is not big enough to avoid exporting policies so I'd prefer to do that, just for the case something happens.
We're going from 10.2.x to 10.2.4 because the platform it's been experimenting failover (couple times in the last 3 months) , so we filled a support ticket, and while f5 hasn't yet tell us the root cause of the problem, it's recommendation was to do this minor upgrade in order to solve some bug about swapping.
We're programming the upgrade this next thursday , if I am still alive I 'll let you know how was it :).
Gracias!
P.S. The provisioning thing it's a good tip, thanks!
