The new level value for all nodes is their current level value plus the difference in levels between the new manager's level and the old manager's level. For example, if you move a subtree to a new location so that the difference in levels between the new manager and the old one is 2, you need to add 2 to the level value of all employees in the affected subtree. Similarly, to amend the path value of all nodes in the subtree, you need to remove the prefix containing the root's old manager's path and substitute it with the new manager's path. This can be achieved simply by using the STUFF function.
