Hi Lee,
Hope you are doing well.
What Sanjay says is correct.
What I usually do now and then I customer ask for this, is:
1. Take a company backup from that specific company.
2. Import in the new standalone installation and check that everything is fine.
3. Go back to the multi-company installation and select companies>Open process wheel>>Open company settings>>Flip B>>Select Inactivate with paste special.
In this case it is still in the database but is not counted as a company in the db.
If you wish to delete, do as Sanjay says.
Sanjay - Thanks
Kind regards,
Martin Arnbom
