Historical data for calculators in custom domains disappears after applying 10.5.1 HF57

Issue:
After applying a 10.5.1 hotfix, the historical data for management module calculators will not be available.
This applies particularly to management module calculators where the management module is part of a custom domain.
Management module calculators in SuperDomain will work as before.
There are not really any particular errors to observe.
Environment:
10.5.1, application of Hotfix 4 or higher.
Cause:
 We introduced a new metadata architecture in 10.5 which removed the domain reference for metrics.
The result of this is to cause a duplicate metric issue when we have metrics with same name, but different domain.
This is particularly likely with virtual metrics.
We provided a fix to store the domain for virtual metrics, that was in 10.5.1 hotfix 4.
However for the virtual metrics already existed before the fix will stay in SuperDomain, since we don't know which domain to attribute the metrics to.
Resolution:
There is not really any workaround for this, for users that only have access to the custom domain, the historical data will be effectively lost.

As we mention above, historical data for calculators in custom domains is not lost but has to be put in SuperDomain due to clashes of duplicate metrics.
