Upgrading Your DataExchange Installation
Instructions for Upgrading an Existing Installation
The following topics explain how to move to a newer version of DataExchange 14:
Before You Upgrade DataExchange
For users who want to move to the current release of DataExchange from an earlier version, the upgrade steps have changed from past releases. You now must uninstall the previous version of DataExchange using a specific set of steps, while also upgrading Zen.
To get ready to upgrade DataExchange, review the following items before proceeding with the steps under
Upgrading DataExchange. In addition, since upgrading requires a new installation, see also the topic
Preparing to Install DataExchange.
DataExchange Readme
We strongly recommend that you read the DataExchange release notes. This readme file provides information that could not be included in the product documentation but may be essential to your installation and use of the product. It is included in a DataExchange 14 installation on 64-bit systems as the file readme_dx.htm in C:\Program Files (x86)\Actian\Zen\Replication\Docs. However, since this file may be updated after the release, its latest version is always posted on the
Actian website.
Windows Administrator Rights
You must have full administrator-level rights on the system where you install DataExchange. For more information, see
Administrator Rights.
Data File Backup
We recommend that you perform a backup of all of your current data files before beginning the upgrade. You may also want to perform a full system backup and test its restoration. A full system backup is best practice before any software installation on a server.
Upgrading DataExchange
Upgrading to the latest version of DataExchange must be done at the same time as upgrading Zen. The following steps apply to upgrades from earlier versions of DataExchange to DataExchange 14.00 and from earlier versions of PSQL to Zen 14.00 and 14.10.
►To upgrade DataExchange
Remember to upgrade all sites used in replication.
1 Deactivate the replication databases on both the Partner Site and First Site.
2 Remove the replication template from the First Site.
3 Stop the Zen services, then delete the replication databases and replication-related files from the following locations:
•C:\Program Files (x86)\Actian\PSQL\Replication\projects
•C:\Program Files (x86)\Actian\PSQL\Replication\templates
4 Uninstall DataExchange on the Partner Site.
5 Uninstall DataExchange on the First Site.
6 Upgrade Zen on the First Site.
7 Upgrade Zen on the Partner Site.
8 Install DataExchange on the First Site machine as the First Site.
9 Install DataExchange on the Partner Site machine as the Partner Site.
10 Use DXDeploy to create a replication project.
11 On the Partner Site, if you are asked to replace existing files for Real Time Backup (RTB), select Save these files before replacing.
12 Initiate replication.
If DataExchange installation fails before the program copies files to the target installation directory, see the %temp% directory of the current login for the installation log file DataExchange_vnn_64_Install.log.
Note If you have been replicating multiple databases, instead of the steps
1–
7 above, consider installing Zen on fresh machines using the ZenCC schema export and import feature to move the databases from their original locations to the new systems. Then continue with steps
8–
12.
