Upgrading Content Deployer
Content Deployer may be currently installed in your environment as one combined Content Deployer microservice, which you can simply upgrade, or as two separate Content Deployer endpoint and Content Deployer worker microservices, which you must combine into a single microservice, because the use of two separate Content Deployer is discontinued as from Tridion Sites 9.6 .
Before you begin
If you are upgrading from SDL Tridion Sites 9 or SDL Tridion Sites 9.1, then before upgrading the Content Deployer, you must have installed the search feature.
