Inroads drainage SDB file editing outside of Inroads

Question

I have two separate inroads drainage files that were created for two separate drainage systems (A & B) of a project. Now, I am trying to analyze them together since system B outfalls into a manhole in System A. 
 Is there a way to merge these two separate inroads files into one file in Inroads? 
 In the past I have been able to open the sdb files in MSAccess and do operations like merge/delete records. Ever since I received an update to MS Access 2013 and I am unable to open the sdb in MS Access. I could probably have IT give me an older version of MS Access and I can go back to my old method. 
 However, I would like to know if there is an option in Inroads to merge two sdb files.

When you copy the data using Access, make sure you copy not only the "Inlets" table, but also all the inlet data out of the "IDs" table as well. Copying over the data from the "InletDesign" table would be optional, as it will be recreated next time a Network Design takes place. I believe you might get the error listed above if the data from the "IDs" table was not copied as well.

InRoads does not have the functionality to merge SDBs. SDBs are in MS Access 95 format, so any edits to the SDB are best done in that version of Access.
