How to Access/Open a .nsf File in the Earlier Versions of HCL Lotus Notes?

HCL Notes has seen numerous major and small updates in the past thirty years. Unfortunately, the NSF files cannot be converted to earlier versions. In this case, an error may occur when you open an NSF file in a Notes version that is older. We cover several approaches to opening the NSF file in earlier versions in this post.
The history of HCL Notes, as we know it now, is extensive. The Lotus Development Corporation originally created Lotus Notes, but IBM acquired it in 1995. In 2018, HCL Technologies acquired IBM Notes, which is now referred to as HCL Notes. Numerous upgrades have been released as a result of these numerous transitions, sometimes with limited compatibility.
When you try to open a.nsf file made in a higher version of Lotus Notes in a lower version of the program, these incompatibilities become most clear. For instance, if you produced a *.nsf file in version 9, you can run into issues while trying to open it in version 8. X.

Upgrading Notes is the simplest option. If, however, it is not possible, keep reading as we outline two other solutions.
How to Open a .nsf File in Lower Versions Manually?
Here are the procedures you can follow to open a *.nsf file in a less recent version.
Stage 1. Make a .nsf File Backup
Make a backup of the *.nsf file before attempting to open it on an older version of Lotus Notes. By doing this, you can be confident that you will still have a copy of the original file in the event that something goes wrong with the process.
Simply make a duplicate of the *.nsf file and store it in a secure location to build a backup. This can be accomplished by making a copy of the file on your computer, copying it to an external hard disc or USB drive, or both.
Stage 2. To Rename the *.nsf File
The *.nsf file’s name must be changed next. This is a crucial step since it will stop you from mistakenly overwriting the original file. Simply right-click on the *.nsf file and choose “Rename” to rename it. Then, give the file a new name, such as *.old, *backup, or any other name for quick identification.
Stage 3. Open the earlier version of Lotus Notes
Open Lotus Notes in a lower version so that you can access the *.nsf file. Double-click the Lotus Notes icon on your desktop or look for it in the Start menu to accomplish this.
Stage 4. Open the old file
Go to File > Database > Open after Lotus Notes has opened. Choose the *.old file that you renamed in Step 2 in the “File name” column. After that, select “Open” to start the file.
Stage 5. Do not upgrade the file
Lotus Notes will detect that the *.old file was made in a more recent version of the program when you try to open it. Then a message will appear asking you if you wish to upgrade the file to the most recent version. When requested to upgrade the file, choose “No” to access the file in its original form.
These steps might open the *.nsf file in a lower version, however, encryption variations or issues with the *.nsf file itself might lead to issues. More critically, you might experience file corruption and lose your data as a result. Additionally, this manual approach needs some technical know-how and work on your part.
Installing Notes 7 is an additional choice because it’s thought to be backward compatible with Notes 8 and 9 editions.
