How to open *.nsf file in lower version lotus notes

Dear Team,

In our Domino setup , We have Lotus nots 9.0 and 8.5.2 or 8.XX Version .

When i create the archive in the Lotus notes 9 same archive i am unable to open in any lower version lotus notes i.e 8.5.2 or 8.XX .Once i upgrade the client to 9 it will open .Is there any way without upgrading the client how to open ?

Getting below error Please suggest how to open these archive .

If it is locally encrypted then replicate it to a server and remove the local encryption. Your earlier client should be able to read the database from there.

The issue is due to your key strength.
