64-bit Notes Client
If you are migrating from/to Notes Domino or NSF files, it is recommended you have a 32-bit Notes client installed on the migration machine. If you only have a 64-bit Notes Client installed on the migration machine, follow the below steps:
Enable migration support with a 64-bit Notes client:
On the Configuration Settings > Optional screen, select the Advanced Options tab at the top.
Check the “I know what I’m doing! Edit Advanced Options” checkbox.

Scroll down to the bottom right of the screen to Custom Options.
Enter /NOTES64 into the Custom Options field.

Click Continue at the top right of the screen.
You have now enabled support with a 64-bit Notes Client.
