Upgrading DataKeeper Cluster Edition from previous versions of DataKeeper Cluster Edition is very straightforward. Simply run the installation process outlined below on all systems. The upgrade process stops the DataKeeper Service, copies the new files to the DataKeeper directory and requires a reboot at the end to load the new DataKeeper driver.
The following information applies to a DataKeeper Cluster Edition upgrade:
- Existing mirrors are not affected by the upgrade and will remain in place.
- It is not necessary to pause or manipulate the mirror(s) in any way before upgrading.
- DataKeeper Cluster Edition licensing is not affected and does not need to be redone after the upgrade.
- IMPORTANT: Before rebooting a WSFC node that is currently the owner of DataKeeper volume resources which are online, it is recommended that all DataKeeper volume resources either be taken offline or moved to a different node/cluster owner.
The DataKeeper Cluster Edition upgrade will be performed on the target systems first. Cluster resources will then be switched over to allow for the upgrade of the original source system.
Upgrading the Target Server
- Using Microsoft Cluster Manager, move all resources to one node/cluster owner so that only one node is the source server.
- Close the DataKeeper UI if it is currently running.
- On each target system, run the setup.exe program distributed with the DataKeeper Cluster Edition product. Setup will detect that you are upgrading your existing DataKeeper product and display a confirmation dialog. Click Yes to continue the upgrade.
- The DataKeeper service will be stopped during the upgrade process. After setup completes, you will be prompted to enter a new DataKeeper license key. When upgrading from a previous version of DataKeeper Cluster Edition, applying new licenses is not required and you may exit the License Manager.
- Reboot your server.
- Bring up the target systems and allow the mirror(s) to resync and return to the Mirroring state.
- Repeat Steps 2-6 for each target system.
Upgrading the Original Source Server
- Using Microsoft Cluster Manager, move all resources to a DataKeeper node that has been upgraded so the source server can be upgraded.
- Once all resources are online on another node and in the mirroring state, repeat the above procedure on the original source system and reboot the server.
- Run the DataKeeper UI to view your existing mirrors.
Reinstalling SIOS DataKeeper Cluster Edition
To reinstall DataKeeper Cluster Edition, perform the same procedures as above, the only exception being that when Setup presents a list of InstallShield options, select Repair.
The Install process also allows repairing the DataKeeper Cluster Edition software. Use this option if the software that was previously installed was accidentally deleted or if the user is performing a point release upgrade. This option copies all the files from the setup folder and prompts the user to reboot the system.
Upgrading from a previous release to DataKeeper v7.6 or later read the considerations for chkdsk.
