Hello Gupta,

your main concern should be, that the new compile procedures produce the same output as your old ones. This includes:
- versions of compilers, DB2 and CICS precompilers, Debug-Tool, etc.
- parameter settings for the compilers, etc, since these normaly differ between installations
- language environments options that rule the runtime behaviour of your applications

The best thing is to copy your sources to the new destination, prepare them new from scratch and then do intense testing.

regards
Christian
