Programming Compatibility - AT&T MERLIN LEGEND Release 3.0 System Programming Manual

Upgrading the System
Inter-Release Compatibility
It is important to understand compatibility between files created on each of the
different versions of SPM, not only for upgrading but also for programming.
Table 2-6 summarizes programming compatibility. (It is assumed that the
majority of the programming is done in surrogate mode and backed up on disk).

The default barrier code and any programmed barrier codes will be carried over

the responsibility of the system manager to change the barrier code length and
the barrier codes if so desired.
