If you use the SOAP for CICS® feature, you can continue to do so;
the feature continues to be fully supported in CICS Transaction Server for z/OS®, Version 3 Release 1,
independently of Web services in CICS.
The SOAP for CICS feature can interoperate with the support for Web
services in CICS TS for z/OS, Version 3.1:
the feature can be the service requester or the service provider.
