I came across this solution which suggests using CTools Bulk Exporter to get the features back into the database so they can be re-exported as smaller features.
Think I've found an alternative solution to get your exported objects back into the database so you can safely disable/remove your features.
- Export everything you want in the database using CTools Bulk Exporter (admin/structure/bulk-export). Put the module it generates into your modules folder (eg. my_exports_module) 2) Disable the features containing the objects you just exported 3) Enable the module CTools Bulk Exporter created for you 4) Download Drush CTools Export Bonus & enable it 5) Run the following drush command: drush cbsa my_exports_module 6) Disable my_exports_module
Tested this with view modes/fields/... created in Display Suite - everything went better than expected :)
