Unfortunately Dynamics CRM 2011 does not support deactivating Territory, If you get a situation where you want to delete the existing territory, you need to first check if it is associated to any accounts or users, if the territory has salespeople(users) or accounts associated with it, the deletion will not succeed, Territory entity have 1:N relationships with “Referential, Restrict Delete” behavior on Account and User, Users cannot directly delete a territory, If the Territory has Users or Accounts associated with it, In order to delete the Territory, need to reassign associated Users and Accounts to different Territory.
Following code helps to re-assign accounts and users territory from one territory to another one.
