Windows AppFabric - renamed server, config now not loading - powershell

Question

My original server was called xyz and the config was as follows:
\xyz\AppFabricConfig\ClusterConfig.xml
We renamed the server and it is now called 123, but the config is still pointing to
\xyz\AppFabricConfig\ClusterConfig.xml
And giving the following error when trying to load:
Use-CacheCluster : ErrorCode<ERRCMS0001>:SubStatus<ES0001>:Error while trying t
o load configuration: An error occurred loading a configuration file: Logon fai
lure: unknown user name or bad password.
(\\xyz\AppFabricConfig\ClusterConfig.xml)
At line:1 char:62
+ Import-Module DistributedCacheAdministration;Use-CacheCluster <<<<
+ CategoryInfo : NotSpecified: (:) [Use-CacheCluster], DataCacheE
xception
+ FullyQualifiedErrorId : ERRCMS0001,Microsoft.ApplicationServer.Caching.C
ommands.UseCacheClusterCommand
I've manually edited the following file:
C:\Windows\System32\AppFabric\DistributedCacheService.exe.config
And set: configuration/dataCacheConfig/clusterConfig connectionString="\123\AppFabricConfig\ClusterConfig.xml"
But its still trying to load from:
\xyz\AppFabricConfig\ClusterConfig.xml
Stumped - close to re-installing, but would really prefer not too!

In hind sight, best way to handle this would've been unconfigure the hosts with remove-cachehost and remove-cacheadmin, rename server and then run config wizard or run add-cachehost and add-cacheadmin.
The connection string is also present in registry, change there also: local machine\software\microsoft\appfabric\v1.0\configuration: connectionstring.
[Edit]
To remove/add the host from cluster configuration, Register-cachehost and unregister-cachehost also need to be run.
