After installing DB2 8.1 and then migrating the instance and the databases
to 8.1, is there anything that needs to be done to remove DB2 7.2 code or
keep 7.2 from starting up? Will there be any ambiguity when issuing DB2
commands as to which version of a DB2 command should be executed? The
operating system is AIX 4.x.
The "Quick Beginnings for DB2 Servers Version 8" manual describes the
migration procedure in detail, but does not mention anything about
removing the old 7.2 code.
There is one thing which is different from pre-version8. DB2 UDB Version8
can coexist with the previous version. So it is much easy to design your
fallback procedure (Of course, this is always the last choice). Since this
wouldn't hurt anything (except your /usr fs has space concern), you'd better
keep the version7 code for some time, if this is production system.
There is no any ambiguity, even you built multiple instances with different
version.
