Anyone know if Adobe Acrobat Pro version 9, 10, & DC are all compatible with each other? If a file is edited and saved with DC can that same file still be edited / saved in version 9 or 10?

I have several different versions of Acrobat Pro I would like to utilize and wondering if they are compatible with each other or if I am going to run into issues if the user that has version 9 edits the file and then a user with version 10 or DC edits it.
