Per the Fair Credit Reporting Act (FCRA), negative entries can only be reported for 7 years PLUS 180 days starting from the DATE OF FIRST DELIQUENCY. Creditors are required to report that DOFD as that is what the reporting period is calculated from. Not all CRA's show the DOFD, you have to call them and ask what it is.
No collection can outlive the obsolescence of the ORIGINAL DEBT because of that DOFD date, which can NOT be changed - not legally anyway. If the date has been updated to make it 'newer', that is illegal re-aging and you can sue the buggers who are doing it. If you find illegal re-aging on your reports, dispute it with the CRA's. You can also dispute directly with the entity that has re-aged per the FACTA amendment to the FCRA.
