What are the best practices when migrating CA XCOM from one Windows Server version to another e.g. Windows Server 2008 to Windows Server 2016 or 2019?
Release : 11.6
Component : CA XCOM Data Transport for Windows
1. Install the latest service pack and patch level of XCOM for Windows 11.6 that is supported for the target Windows Server version per steps below:
a. Currently, SP03 is the latest Service Pack which is supported for both Windows Server 2016 & 2019.

d. The SP03 release is version r11.6.20035.
After the install, install the latest patch to avoid any known problems. XCOM patches are cumulative so only the latest patch needs to be installed.

2. In general, unless the old and new servers are running identical XCOM versions, the best practice advice for the migration of any configuration settings from an old XCOM server to a new XCOM server would be that the new server should not simply have its configuration files replaced with backed-up versions from the old server. Instead, the steps should be:
a. Review what is currently in the xcom.glb and xcom.cnf files on the old server and use those files as a guide to modify the new xcom.glb and xcom.cnf. The same advice applies to any other configuration files e.g. configssl.cnf.
b. If using XCOM pre-processing or post-processing scripts on the old server the versions of those equivalent scripts on the new server will need to be modified accordingly.
