Migration for alert_grouping_parameters depends on an import from a data resource #988
Description
I am prepping to migrate from alert_grouping_parameters to the pagerduty_alert_grouping_setting resource to take advantage of content_based_intelligent grouping. I am referencing the instructions here.
The migration instructions include setting up a data resource to link to the already existing alert grouping objects that I assume PD has migrated behind the scenes, and then uses an import block to link that to the new resource.
My understanding of terraform is that a data resource cannot be used as the source of an import block, and this approach fails with Unsuitable value: value must be known.
Are there additional steps or assumptions I am missing here to make this migration path work?
