Mapping metrics to exisiting scorecards

[JCH]

we are migrating from 7.3 to 8.4.1.
All metrics and scorecards were successfully migrated and visible within Metric Studio.
We are having difficulty updating the metrics based on data (cube) updates.
How do the import sources for the metrics get udpated to recognize the udpated cube sources?

Wse ahve used Metrics Designer and can create 'new' metrics and 'new' scorecards which can be udpated with a data (cube) update, but have not been able to 'map' exisitng cubes to new data sources, or even 'new' metrics to exisiting scorecards.

How can this task be accomplished?

thanks in advance.
