Please note in particular that during the transition to the new system on 1st January 2021, SAP, you will lose access to Pagaweb. Salary slips from 2020 or earlier will unfortunately not be available in the new self-service portal from DFØ. You can also not log in to Pagaweb after the New Year.
If necessary, you must therefore download your old payslips before the New Year, as well as any other historical information you think you might need.
Relevant information about the new system can be found here (regretfully Norwegian only):
