Hey,
Outlook and Lotus Notes have different internal formats, which is the main reason direct migration of contacts sometimes fails. CSV exports generally compress contact data and create field-mapping problems in Lotus Notes. It is a better method to first change Outlook contacts to the vCard format and then convert them to Lotus Notes-compatible files using a
VCF to NSF converter.
A correct solution should:
Keep all the contact fields
Not have duplicate or missing entries
Create a fully Notes-compatible NSF file
When a similar migration was carried out, the DataVare vCard Export Import tool efficiently converted vCard contacts into the Lotus Notes-accessible NSF format, so the contacts were instantly available in Lotus Notes without the need for additional cleanup.
