Are the SQL Server instances stand-alones or clustered? <br />
If they are &nbsp;clustered instances then stop SQL Server service and change the SQL IP Address (all this tasks need to be performed in the Failover Cluster Manager snap-in). The start the SQL Server with the new IP address.<br />
If they are stand-alones, stop the SQL Server service and change the IP locally before start again the SQL Server service.<br />
<br />
For AG, you'll need to drop the listener from the Principal replica and recreate it giving the new IP address.

So you have 2 stand-alone SQL Server instances, right?<br />
YES.<br />
<br />
It should be DBs are replicated through AG?<br />
YES

Microsoft SQL Server is a suite of relational database management system (RDBMS) products providing multi-user database access functionality.SQL Server is available in multiple versions, typically identified by release year, and versions are subdivided into editions to distinguish between product functionality.

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
