It looks like there is some migration issues once migrating from cisco asa.
Looks like if the objects contains -all, -to, -in the objects might not be migrated correct, and some objects are renamed, but not for nat policy. It looks like the objects with -all is not created in the migrated policy.
If migrating several contexts please consider that asdm objects DM_INLINE_NETWORK and DM_INLINE_TCP is auto genrated objects for asdm and is there created objects using CSM these could also have the same name but with diferent content.
Feel free to contact me if you need more details on it.
