Steps to update CRM with accepted connects and merge into central contacts database.
Sync up Connects
As recipients of your connect requests accept, you would start seeing them under your network as 1st degree connects. It may be useful to sync status and also update contact details like Email and Phone number if they are on record with LinkedIn and your contact has shared them.
Hit Sync contacts to automatically update status of your connect requests. Optionally also run refresh of contact details to read profiles, create a summary and add them to CRM. You can set status as well for easier search in future.
