we have small Access DB developed in 2000s, still up and running. few users access from office 2013 and recently i noticed some users access from Office 365. I'm not expert on DB or Access, but we see some errors/warnings message while running the app. my manager is asking if we can upgrade it, if yes then what is the right way to do so. do we have to create all the front end forms and back end databases in O365 ?
TIA
