Features removed

The following features, which are available in ESB runtimes, are removed from the Micro Integrator of EI 7.1 because they are not frequently used.

Feature Description Alternative
Management Console WSO2 Integration Studio is the recommended tool for developing integration solutions. The monitoring capabilities available in the management console (of the ESB profile) are available through the new Micro Integrator dashboard. Micro Integrator Dashboard
Multitenancy This is not a widely used feature in the ESB profile. Multitenancy does not suit the world of microservices or micro integrations. -
Svn based Dep-sync This is not a widely used feature in the ESB profile, and is not recommended for use. Third-party offering like rsync
RDBMS-based Registry - File system based Registry
Rule Mediator The rule mediator has been removed from EI 7.1.0 as it is not widely used. -
HL7 Message Store In previous ESBs, an HL7 Message Store could be configured using the custom message store implementation. Due to limited capabilities and tight coupling with the Hl7 console (which was previously available in the management console), this functionality is not available in EI 7.x. -
