change password psadmin account

We run PeopleSoft CRM (PT 8.51) on Windows and a MSSQL server database

We need to change the psadmin password. We followed the steps below, but it didnt work properly

- connect with MSSQL Server Studio tot database and connect with datamover at the same time.

- change the psadmin (database user) password in MSSQL

- run in datamover a script like:
update PSACCESSPRFL set ACCESSID = 'psadmin', ACCESSPSWD = 'newpassword', ENCRYPTED = '*';

encrypt psadmin;

- run psadmin.exe ,start 'edit configuration' change the connectId pwd likewise

After this the PeopleSoft-application still worked properly, however logging in in the App.Designer and DataMover became impossible.

Is there any proper documentation about changing the psadmin password?
