Compare this release with previous ESBs¶
Given below is a comparison of the Micro Integrator of EI 7.1 and the previous WSO2 ESB runtimes. Note that the Micro Integrator of EI 7.1 is the latest, most improved version of the WSO2 ESB runtime.
If you are migrating from a previous ESB, this comparison will help you understand the important changes in the Micro Integrator that will impact your migration.
Note
The following comparison is applicable to the following versions of the WSO2 ESB runtime:

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. | - |
