In order to upgrade the InterChange Server Express system, you must make
sure that the system is in a quiescent state. This means that all
in-progress events should be completed and all in-doubt transactions are
resolved before backing up the environment and performing the upgrade
procedure.
If you have previously installed the 4.3 release to your system, and
you run the Installer to upgrade to the 4.3.1 release, the
Installer does the following:
- The Installer does not drop your existing database.
- Installer drops your existing repository. Existing relationship
tables are retained; however, repository definitions for relationship
tables are temporarily removed.
- The Installer re-creates the repository, using the repository definitions
of your upgrade release.
If you have previously installed Express V4.3.1 to your
system, and you run the Installer to upgrade to Express Plus
V4.3.1, the Installer does the following:
- Installs the adapters you have selected
- Adds Process Designer Express to your toolset
- The Installer does not drop your existing database
- The Installer retains your existing repository and does not redeploy it,
unless you have not previously installed the collaboration and are now
installing it for the first time as part of your upgrade. If you have
not previously installed the collaboration and are selecting it now for the
first time, the Installer deploys the Express Plus 4.3.1
repository.
