1. A computing system comprising:
a source database system comprising N hosts and a first plurality of servers, where N is an integer greater than one, the source database system comprising:
a first memory storing first processor-executable program code; anda first processor to execute the first processor-executable program code in order to cause the source database system to:
create a backup of the source database system; and a target database system comprising M hosts, where M is an integer less than N, the target database system comprising:
a second memory storing second processor-executable program code; anda second processor to execute the second processor-executable program code in order to cause the target database system to:
configure the target database system to include the first plurality of servers; andperform a database recovery of the target database system using the backup of the source database system.
