Hello Nixomohan,

Features are not included in a content database, they are only referenced there.
FeatureAdmin is working via API, this means, you need to connect your content DB either to SP2010 or to SP2013 first, then you can remove/deactivate the features in it.

It usually is best to deactivate a feature, before migrating a content database to another farm, where this feature is not available.

You can bulk deactivate features with the featureadmin in SP2010.

Are your features still available in the SP2010 farm? Then I would recommend that you reconnect your content db to SP2010 and deactivate them in SP2010.

If your SP2010 farm is not available any more, make a backup of your content db. Then, connect the content-db to sp2013, even though the test was not successful.
In SP2013, remove the orphaned features with featureadmin.

If a feature can be removed at all or if it can be cleanly removed depends how it is implemented.

If a feature is not well developed, it is possible, that a sitecollection does not work anymore, if the feature is not available any more, no matter, if it was deactivated or not.

If you want to remove/deactivate a feature, when the feature is actually not available any more, this should usually only cause a problem, if the feature had a feature receiver for feature deactivating or feature uninstalling.

I hope, this answers some of your questions.

Kind Regards,
