Acrobat DC Pro Compatible with prior 2 versions of Acrobat?

Hello, we have Acrobat Pro DC for our law firm. Our local court system just sent a notice requiring that "all PDF files are compatible with the prior two versions of Adobe Acrobat". If we continue to create PDFs in our current Arocbat Pro DC program, will they be compatible with the prior 2 versions of Adobe Acrobat? Thanks
