I was looking for a document hat may outline how to change the CME and CUE passwords properly in order not to break any connections between the systems. |

Good reference
Here are some ideas from this doc:

Problem: User Cannot Log In Through the Cisco Unity Express Graphical User Interface (GUI)
The Cisco Unity Express user cannot log in through the Cisco Unity Express GUI and receives the Cisco Unity Express has lost contact with the Host router. Enter the new CCME Web Administrator username and password error message.
Complete these steps in order to resolve this problem:
1.
Check in order to see if the Cisco CallManager Express configuration misses any of the configuration commands mentioned in this document.
2.
If the configuration is correct, the Cisco CallManager Express router might miss the default-gateway configuration. This might happen if the administrator reloads the router without saving the configuration. Check the Cisco CallManager Express configuration for IP connectivity to Cisco Cisco Unity Express.
3.
This errror message is also seen when the administrator decides to change the Cisco CallManager Express web administrator username and password, and the new name and password is not updated in the Cisco Unity Express system. Use the procedure mentioned in Unity Express GUI Password Recovery in order to update the system with new Cisco CallManager Express username and password.
4.
Use the service-module service-engine slot/port reload command in order to reload the Cisco Unity Express module.
Note: A reboot of the Cisco Unity Express module does not require a reboot of the router. The Cisco Unity Express module and the router can be rebooted independently of each other. However, if you reboot the router, no calls reach the module until IP connectivity is reestablished between the router and the module. Always perform a shutdown of the module before you power-cycle the router in order to avoid data loss or file corruption.
Refer to Troubleshooting Cisco Unity Express System Features for more information on how to troubleshoot CallManager Express/Cisco Unity Express configuration issues.
