Phil, Since no one else has asked, why are you going from internal to external CFs? What is the hardware involved for both your regular lpars and your CF lpars?
The last thing you want is for your CFs to be slower than the CPs.

I ran the sizer tool and have the info for the new sizes. However, the INITSIZE and MINSIZE values have me challenged. For most structures, the current allocation doesn't specify a value for either parameter or the specified value appears to be a poor choice. For instance, the book says that SIZE should be no more than 1.5 - 2.0 times INITSIZE but we have some where SIZE is 30 times INITSIZE. My questions are; 1) Should INITSIZE and MINSIZE always be specified? 2) Are all structures 'eligible' to be defined with these parameters? 3) Besides the ratio specified above, are their any guidelines for the definitions? 4) The sizer tool is based on current allocation which may not be ideal. Is there a way to confirm if I have the best fit? 5) Besides the manual "Setting up a Sysplex" is there more doc where I can find additional info? Any suggestions or thoughts will be appreciated. Thanks.
