Migrating Multiple Databases
The second method of migrating TurboIMAGE databases and applications is
to use the STORE/RESTORE facility and DIRMIG. This method allows you to
move all the databases and application programs on your system at the
same time. In addition, DIRMIG recreates your existing account structure
on the MPE/iX system. All user identities, passwords, UDCs, and
permissions can be moved intact from an MPE V/E-based system to an
MPE/iX-based system.
There are five basic steps to migrating a block of databases and
application programs.
1. Disable ILR, if it has been enabled for any of the databases to be
migrated.
2. Perform a full SYSDUMP of the system you want to migrate.
3. Install the SYSDUMP tape on the tape drive of the MPE/iX-based
system you are moving onto.
4. Run the DIRMIG utility and specify the files and accounts you want
recreated on the MPE/iX machine.
5. Perform a STORE of all the database files from the MPE V/E-based
system and restore the files on the MPE/iX system.
After completing the steps listed, you should have a duplicate of your
MPE V/E directory, databases, and application programs installed on the
MPE/iX system. You will be able to run your existing applications (in
CM) and access the databases in much the same manner as you did on the
MPE V/E-based system.
NOTE For more information about using DIRMIG to migrate your databases,
