You can upgrade a model and all the fragments that it owns
to the latest version of the product at the same time, instead of
individually. Upgrading a model and its owned fragments at the same
time saves time and memory resources because the model and fragments
do not have to go through the silent migration process each time that
you load the model.
About this task
Upgrading the entire model at one time is helpful when you
have a large model that is based on an older version of the product,
and that is divided into thousands of owned fragments. When you open
this type of model in the newest version of the product, all the fragments
load silently and migrate to the latest underlying schema of the product.
This migration process can take a long time and use a large amount
of system resources depending on the size of the model and how it
is divided into fragments.
If you make a simple change to the model,
such as modifying one fragment, when you save the model and underlying
fragment, the only artifacts that save in the new format are the model
itself and the specific fragment that you modified. All the other
fragments remain in the older format and, therefore, must go through
the silent migration process again the next time that you load the
model. However, you can force the model and all related fragments
to upgrade so that every artifact is saved as the latest version at
the same time.
To upgrade a model and its owned fragments at
the same time:
