I am merging info from one feature to another feature as the 2 features represents same thing but they have different information (e.g. one feature will have a set of attributes filled in and other feature will have another set of fields filled in). These features are collected in the field and have attachments and related records. I am able to grab all the info, update/merge attributes as required. I am also able to re-assign the related table records by updating the parentglobalid.
I can query the feature for attachments. However, I can't find a way to update the attachments linkage/association to parent feature. I am looking for doing through REST API.
Any thoughts on how can I achieve it?
