SCM 7.0 to SCM 7.0 EHP3 system preparation

Hi Experts,

I am going to upgrade the SCM 7.0 to SCM 7.0 EHP3

what steps should I take care before the activity

1) Should I have to stop livecache before the upgrade?

2) Maxdb (7.7.06.09) should be upgraded for Livecache from current level to suit for SCM 7.0 EHP3. If so , please give me the maxdb upgrade steps and suitable version for SCM 7.0 EHP3?

3) This one should be called upgrade (or) update?

4) can we upgrade the livecache separately and SCM alone now?

5) Should optimizer be disconnected from the system? - the optimizer is being shared with other systems as well

Please clear all my doubts

I will appreciate your help and guidance

Thanks a ton
