When you transfer a contact, the existing EHR connection is removed for any associated site. This is true if you retire or transfer the sites. For more information, see Transfer active contacts.

A dialog window notifies you if the site has existing Subject-Patient links associated with the current connector.

You can still transfer the contact if you don’t remove the links, but site users are required to relink subjects manually before importing additional EHR data.

When you retire a site, the existing EHR connection information is preserved. If the site is reactivated, the connection is also reactivated.

For more information, see Retire a site at a study level.

All subject links are removed during the study decommission process.

For more information, see Decommission a Production study.

Recommissioning a study requires you to follow the same steps you used to initially enable it for EHR data import.

For more information about recommissioning a study, see Recommission a study.
