+## Reassignment of Manager from Group and User Tables to New Manager for Outgoing/Retiring Manager
+
+Automatically reassigns all groups and users managed by a retiring manager to a new manager and deactivates the outgoing manager’s **sys_user** record.
+
+- Ensures transition by updating manager references in both user and group tables before disabling the old manager’s access.  
+- Uses a Background Script to perform the following actions:
+  - Updates all groups where the old manager is assigned   
+  - Updates all users reporting to the old manager by new manager 
+  - Make old manager’s user record inactive in **sys_user** record
+
+### Prerequisites :
+- Keep old manager's and new manager's sys_ids ready
+- Navigate to System Definition → Scripts - Background
+- Click New and paste the script. In the script Replace with your requirement: 
+  - var oldManagerSysId = `<Include sys id of old Manager >`
+  - var newManagerSysId =  `<Include sys id of New Manager >`
+- Run Script
