How to convert a "Calculated application service" in to a tag based application service?

[chaithra10]

We have been using "Calculated application services" in our infra from a long time, now we are working on implementing "Service mapping". for cloud based apps - we are using "tag based application service" creation method and we have built tag based app services. But  the same app already exists in "Calculated app " class creating duplicates.

Could you someone guide me on how to address these duplicates effectively? We also need to ensure this doesn't break the existing relationships and any ITSM processes.

Hey Chaithra,

Manually: I've done it by reclassifying records from calculated to cmdb_ci_service_auto. Then you can use app service wizard to redefine mapping using tag-based approach.

"Automatically": Similarly to a manual approach, you can script that logic and do the same 2 step approach or convert directly to a tag-based class. Compare the attributes that are populated for tag-based services vs calculated ones, it should give you a pretty good idea what needs to be changed.

Cheers,

Alexey

when I do this, I am loosing the existing relationship end points and and svc_ci_assoc entry for old/exising CIs on calculated app service and they are not appearing in "Impacted service" on Inciden and change. how do I retain the old svc_ci_assoc and end points of old Cis and as well append the new rels via tags.

If I understand you correctly, you're trying to achieve some sort of hybrid service mapping, which is not supported currently. I'd suggest supplying correct set of tags to those existing CIs, so the new tag-based mapping picks them up once mapping is completed.

yes! There is an UI action update set loaded, I had to commit it and that enabled "Convert CSDM Application service " that does the 1st 2 steps automatically..
