Migrating the V4 Model
||This task shows how
to migrate V4 models
to V5. This task should only be attempted after all the other tasks
in this section have been completed.
this task you should make sure that options are correctly set in your
project resource management file. These options help you control which
portions of a model you want to migrate - if you want to migrate only
certain parts of it. If your V4 model has data from Piping and
Instrumentation Diagrams, Piping Design, HVAC Design, Structures and
Equipment Arrangement, you can decide which type of data you want to
migrate by setting these options. If you choose to only migrate Tubing
data, then you can do so. See
Understanding Project Resource Management, AEC V4 V5 Migration section,
on how to set the options.
||Move your V4 model (by ftp or any
other means) to the same platform as V5, in this case Windows.
||Set the following environment variables.
(In Unix, you "export" instead of "set".)
where XXX is the directory path to your installation.
- AECMIGR_PROJECT = ProjectXXX where ProjectXXX is the name
of your project resource management file.
- MIGRATION_MASTER_APPLI = AEC_MDLR For Tubing
Design leave the second value out. Enter only MIGRATION_MASTER_APPLI =
For Tubing Design, when migrating models, the project resource
management file must reference a proper tube dimensions table in order to
map outside diameter to nominal size. In the PRM file find the 'TubingDimensions'
entry and correct the location if necessary.
||You now need to launch the V4 to
V5 migration batch (the DataLifeCycle batch). Launching the batch is
explained in the Infrastructure documentation:
Infrastructure>V4Integration>Migrating from V4 to V5 in Batch Mode>How
to Launch the V4 to V5 Migration Batch.
NOTE: The Migration
Interface pane of the Migration Outputs dialog box must show
as the interface: CATIAecMigration. The Migration
Outputs dialog box settings are explained in the task Migration
Batch, which you can get to through the link given above.
||The V4 model will be migrated as
several documents, and each one will display in the specifications tree
when you expand it.. Each object in the document will be in a separate
document. To open the document click File - Open on the application menu
bar and navigate to the directory you specified in the Target Directory
field. The document with the same name as the V4 document is the "master"
document, which contains (references to) all the components. Other
documents underneath it will have identifying letters - such as EQ for
Equipment - to indicate what they contain. The document will contain
references to all parts - piping or tubing documents, for instance, will
contain references to all parts that are in the piping or tubing line.
Similarly, equipment documents will contain references to parts and nozzles
that make up the equipment. You need all the files to recreate the
