Importing configuration is moving all the previous data to a new term or session as the case may be.
Step 1: Click on 'Import Configurations' on the left-side of the page under 'Admin'.
Step 2: Select the term which you want to import from the drop-down, for example, From First Term, 2018/2019 To Second Term, 2018/2019, then click on 'Import Configurations'.
NB: If you are importing the configurations from a previous session to a new session, for example, From Third Term, 2018/2019 To First Term, 2019/2020 then you MUST carefully uncheck Import Class Members, Import Form Teachers, and Import Subject Teachers. This is because the data of the students/teachers will still remain in the same class during the new session.
