Appendix A 199
MPE/V to MPE/iX Migration
File Conversion Guidelines
This new NMCONFIG.PUB.SYS file contains your NS configuration in a
format acceptable to MPE/iX. You can now run NMMGR to configure
the DTS subsystem, and to perform any needed modifications to the NS
configuration. See “Reconfiguration Guidelines” later in this appendix.
Updating From a Previous MPE/iX Version
Updating from an earlier version of MPE/iX at the same time migrating
from NS 3000/V to NS 3000/iX, you will need to make a choice between
reconfiguring Distributed Terminal Subsystem (DTS) and reconfiguring
the NS network. The choice is necessary because MPE/V versions of
NMCONFIG.PUB.SYS files do not include DTS configuration values.
The circumstances of the installation determine which configuration
values to preserve. If the NS network is complex, you may decide to
convert the existing MPE/V configuration files, and reconfigure DTS. In
this case you should follow the steps under “File Conversion
Guidelines” earlier in this appendix.
If, on the other hand, your DTS configuration is extensive, you may
decide to migrate your existing MPE/iX configuration files to the new
version of MPE/iX. You will then need to redo your NS network
configuration so that both the NS and DTS configurations are contained
in a single, valid, MPE/iX NMCONFIG.PUB.SYS file. In any case, you will
need to reconfigure either NS or DTS if you are both updating MPE/iX
and converting from an NS 3000/V network to an NS 3000/iX network.
