Inconsistent Data in tables User [ sys_user ] and Group[ sys_user_group] , Contacts [ customer_contact ] related tables after Instance Clone, which is performed before 1st May 2020DescriptionUnexpected result after clone in tables User [ sys_user ] and Group[ sys_user_group] , Contacts [ customer_contact ] related tables. Through this problem the options "Preserve users and related tables" was set as unchecked by default on the clone request form. Please note : Option "Preserve users and related tables" still remains disabled until the fix for the PRB1351704 is deployed.Steps to Reproduce After 7th Feb 2020 & Before 1st May 2020 the "Preserve users and related tables" functionality was enabled. When submitting Clone request by default "Preserve users and related tables" will be checked, as a result, this will Exclude and Preserve 'User' related tables data in the target instance. The following tables are affected: sys_usersys_user_groupsys_user_grmembersys_user_rolesys_user_has_rolecustomer_contact Afterward, we experienced PRB1391196 - Clone with the option checked "Preserve users and related tables" leaves the record with missing references on tables related to role inheritance on the target instance. The decision was made to disable the feature until it is fixed. After 1st May 2020: We disabled the "Preserve users and related tables" functionality. [Even if this "Preserve users and related tables" checked OR NOT, this will not Exclude and Preserve User related data in target instance]. Our sincere apologies for the quick changes in the cloning process, we will be adding this information in Clone Change Requests too. WorkaroundThe next question is what is the best way to Exclude and Preserve Users n related tables now? Please create the following Excludes: sys_usersys_user_rolesys_user_has_rolesys_user_groupsys_user_grmembersys_group_has_rolesys_user_role_containscustomer_contact [Only if you have the Customer Service Management plugin installed] This will not bring over any users from the source instance or any of the references to groups and roles, but now you need to preserve the sys_user in the target instance, but something that many people forget is you also need to preserve roles, groups and also the links from users to roles and groups, this is a common mistake and after cloning you are missing the admin role and cannot log in, this is because the links to the roles are missing. Now you should create these Preservers: (Add any conditions depending on your requirements) sys_usersys_user_rolesys_user_groupsys_user_grmembersys_user_has_rolesys_group_has_rolesys_user_role_containscustomer_contact [Only if you have the Customer Service Management plugin installed] This will preserve all the users, roles, and groups in the target instance, but it will also preserve the permissions of those users to those groups and roles. Please note : Option "Preserve users and related tables" still remains disabled until the fix for the PRB1351704 is deployed.Related Problem: PRB1387853
