Hi Shanahas,
There is nothing as such that for C-CEE Add-on you need to use Resource minimized.
Upgrade strategy depends on the system resources and how much downtime customer can afford for business.
Many of the upgrades follow downtime minimized approach.
For C-CEE addon you may need to refer below SAP note
Note 1260937 - C-CEE: Upgrade to SAP ECC 600 EHP 4/5/6
Also refer SAP upgrade guide for your release.
Hope this helps.
