Hi @NarasimhaRC
Regarding Install: refer this SN Doc
Activate the ITSM Roles plugin on a subproduction environment and test the functionality before requesting activation in the production environment. For assistance, contact the ServiceNow Professional Services team.
Procedure
- Navigate to All > System Applications > All Available Applications > All.
- Select Request plugin to open the Activate Plugin form on Now Support.
- On the Activate Plugin form, provide the following information.
Activate Plugin formField Description
What is your target instance | Select the instance that you want to activate the plugin on. |
Which plugin would you like to activate | Select the name of the plugin to activate. Note:If the system doesn't list the plugin you want or if you're activating the plugin on an OEM or on-premise instance, select the Plugin I'm looking for is not listed check box and then enter the name of the plugin. |

Regarding Uninstall or rollback:
Once a plugin is activated, you cannot disable, deactivate, or uninstall it. ServiceNow doesn’t provide a supported method to reverse the installation.
You are installing it subprod first. If you face any problem, either backout related update set, or you can clone it by prod that never had the plugin activated.
