You use the Datacap installation
program to upgrade Datacap 8.0.1,
8.1.0, and 9.0 Datacap software
to Datacap 9.0.1.
Your customized code might not be retained from the previous version.
About this task
Upgrade a production
client/server environment by installing Datacap software on newly
provisioned computers and migrating the application to a new environment.
You can upgrade Datacap software in
place (without removing an existing older version) in non-production
environments by installing Datacap 9.0.1
on a computer with Datacap 8.1
or 8.0.1. Complete the following general steps to upgrade and migrate
your Datacap applications.
Each step can require some extensive installation or customization
tasks.
Procedure
To upgrade software and migrate applications from a previous
release:
- Configure a Datacap 9.0.1
test environment:
- In a non-production development environment, install Datacap 9.0.1. It
is possible to install Datacap 9.0.1 on a system with existing Datacap
software installed. Use this installation to deploy, configure, and
test any modifications.
You might also use new
interfaces that are available on Datacap 9.0.1. For example,
since Version 8.0.1, the Datacap Web Client and IBM Content Navigator administrative clients
replaced the Datacap thick
client. For installation details, see Installing, configuring, and running Datacap in a client/server
environment .
- Review the installation topics that describe the export
and import of encryption keys. You must have FIPS encryption as of
version 8.1.0 for password protection.
- Migrate and copy your customizations from your previous Datacap environment to this
test environment.
- Open Datacap Studio and
determine whether any existing rules or actions were eliminated or
deprecated in the new release. Deprecated actions are designated
as Private and they cannot run in the Test tab
in Datacap Studio. But they
can run in your updated applications. In a subsequent release, remove
these deprecated actions from the application.
- Modify your customized settings as needed.
- Update the code and customized user interfaces that
were not fully migrated to maintain your current level of function.
- Apply any new features in the updated software version
that you want to implement.
- Test your updated applications and configuration in
the development environment against your current production system. You run this parallel testing to validate features, performance,
connectivity, and volume throughput. For example,
ensure that program communication works as intended between servers
and clients, web or otherwise. FIPS encryption is new as of Datacap 8.1.0 and is documented
in the client/server installation topics. Encryption keys must match
on all computers in the configuration to protect passwords for program-related
accounts.
- Configure a Version 9.0.1 production environment:
- Install and verify the new version of Datacap software on computers
that are not running current Datacap software. For
installation details, see Installing, configuring, and running Datacap in a client/server
environment.
- Copy the migrated or newly customized applications from
your test environment to the newly installed release. For
details on migrating database information, see Copying the application to the Datacap server.
- Test and verify the functions of the new configuration
before you deploy it into production.
- Ensure that users can connect to the newly updated production-ready
configuration.
- Switch to the newly configured system for production
use. For example, you might disable user activity permanently
on the previous production system and ensure that new server IP addresses
are correctly designated.
