I'm using SCIM to sync Azure AD account information to System-AAA.
However, certain users need to get out of sync with the old user and resync with another new user.
the AzureAD account taro.yamada@azuread has been set to be resynchronized with the System-AAA account taro.yamada-before@systemAAA using SCIM. A new System-AAA account taro.yamada-after@systemAAA is created.
Now, taro.yamada@azuread needs to be resynchronized with taro.yamada-after@systemAAA.
In this case, it seems that it is theoretically possible with the following procedure,
but I didn't know how to do step 2).
How can I do it? Is there a way?
1) Delete the "externalId" of taro.yamada-before@systemAAA on the System-AAA side.
2) Delete the System-AAA "id" (the one described as "Target ID" on the AzureAD screen) stored on the AzureAD side.
3) Send a Create request (SCIM) from AzureAD to System-AAA for taro.yamada@azuread to be created as taro.yamada-after@systemAAA
