Release notes for the latest v2.5.x CPM release

In order to upgrade to v2.5.x, please use one of the methods below:

1) AMI upgrade method . Use the upgrade instructions in chapter 1.3.5 "Upgrading the CPM Server Instance" at https://n2ws.com/support/documentation/introduction-to-cpm#13 
   This method must be used if you have a version older than v2.5.0

-or-

2) Patch upgrade method - use the patch file attached at the bottom of this KB (unzip it first).
    Patch can only be used if you already have v2.5.0 or newer.

- No backups, DR or S3 copies should be running or scheduled to run while installing the patch
  • Please take steps such as disabling schedules to ensure policies will not try to run until the upgrade is complete.
- Patch can be applied by using the "CPM patches" link at the bottom of the GUI:


- Note it may take a few minutes for the CPM GUI to become responsive after installation.


For both upgrade methods, please give attention to these details:
1. Due to the new functionality in v2.5, you may need to update your permission policies. Please see the JSON templates attached to this KB: https://support.n2ws.com/portal/kb/articles/what-are-the-required-minimal-aws-permissions-roles-for-cpm-operation

2. it is now a requirement to attach an IAM role to the CPM server instance.

3. After the latest version is installed, please manually upgrade VSS Agents by downloading the thin backup agent from the upgraded CPM server and reinstalling within the instance OS (if your VSS Agents are older than v2.4)


CPM CLI and RESTful API have been updated to v1.2:
