Notes:
–G5 base CF level code is CF Level 6 and can be upgraded to CF Level 11
–G6 base CF level code is CF Level 8 and can be upgraded to CF Level 11
–z900 base CF level code is CF Level 9
–z800, z890 and z990 base CF level code is CF Level 12
–Detailed information regarding CF Levels can be found in Coupling Facility Level (CF LEVEL) Considerations at ibm.com/s390/pso/cftable.html
*G3, G4, G5 and G6 only **zSeries required
Please note that although a particular back level machine may be updated to a more current CFCC level, NOT all the functions of that CFCC level may be able to run on that hardware platform, i.e., G3/G4 can be upgraded to CF Level 8 but it cannot use dynamic ICF expansion into shared ICF pool.
