What do I need to know if my site has Enhanced Search Service Enabled and is transporting between environments?

Environment:

Environmental, Migration of all Oracle B2C Service sites,

Oracle Cloud Infrastructure (OCI)

Resolution:

Customers that leverage the Enhanced Search Service may experience incomplete search results for a short period of time after their site(s) has transported into a new data center.  The data in the incidents table needs to be indexed in the new datacenter which can take some time (about 4 hours for 1 million incidents).  

How do I know if Enhanced Search Service is being used for my site?

• Enhanced Search Service is only available for customers on 19B MP1 or later and has been enabled for a subset of customers. 
• Enhanced Search Service will be enabled for newly provisioned sites created on 20A or later.
• Enhanced Search Service will be enabled automatically upon update to 20B or later.
