I have a SQL query which runs under 1 minute on SQL Server 2012 SP3 but run over 2 hrs on SQL Server 2016 SP1.on Server side both server runs on identical hardware which is virtual server (VMWare),2 sockets 16 vCPUs with 170GB RAM allocated to SQL Server.The SQL2012 server runs on EMC SAN and SQL2016 runs on Flash drive.The execution plan on both server are different.

Can you please help to troubleshoot this performance issue.

Thanks in advance.
