CICS: NEWCOPY Vs PHASEIN

What is the difference between the following usages in the CICS region:

a) CEMT SET PROGRAM(xxxxxxxx) NEWCOPY
b) CEMT SET PROGRAM(xxxxxxxx) PHASEIN



NEwcopy 
CICS is to use a new copy of the program when all the transactions currently using the program have finished (RESCOUNT equal to zero). CICS loads the new version either from the DFHRPL library concatenation or uses an LPA-resident version, depending on the PRIVATE or SHARED options. PRIVATE is the default setting. 

PHasein 
CICS is to use a new copy of the program now for all new transaction requests. CICS continues to use the old copy for all currently running transactions until they have finished (RESCOUNT equal to zero). CICS loads the new version either from the DFHRPL library concatenation or uses an LPA-resident version, depending on the PRIVATE or SHARED options. PRIVATE is the default setting.
