.adp conversion to .accdb
I have an old .adp MS Access and need to convert it to .accdb. It can be opened in MS Access 2007 version but there was no save-as or publishing option for .mdb. I have also tried creating a new database .accdb file in MS Access through Microsoft 365, then utilized external data by import or link the elements from this .adp file. But it didn't work either. MS Access pops up this error for everything I tried. How can I convert the .adp file to a .mbd or .accdb? Thank you.
