Besides program directories and installation stuff, have you looked at both the COBOL and the LE "Migration Guides"/
In general, I would recommend upgrading the operating system (with LE) first and get it "stable" in all environments (LPARs, whatever). After that is stable (and all your old COBOL code *should* run as expected), then upgrade the compiler in a separate step. Assuming that you really are ENTIRELY at "IBM COBOL for OS/390 & VM 2.2.0" for all your compiled COBOL object code, I wouldn't expect any problems. If you actually DO have older object code (especially OS/VS COBOL or possibly even VS COBOL II object code) then more research may be needed before your conversion effort.
