CLM Upgrade 6.0.2 - Create index files for VVCMODEL.VERSION table in which databases?

In the roadmap that I am following,

step 8: Create index files for VVCMODEL.VERSION

ALTER TABLE VVCMODEL.VERSION ALTER COLUMN CONCEPT NVARCHAR(450) NOT NULL
ALTER TABLE VVCMODEL.VERSION ALTER COLUMN STORAGE NVARCHAR(450) NULL

CREATE  INDEX VERSION_CONCEPT_DX ON VVCMODEL.VERSION (CONCEPT)
CREATE  INDEX VERSION_STORAGE_DX ON VVCMODEL.VERSION (STORAGE)

does not specify which database should I do it.

I noticed that the table exists in the database JTS, CCM, QM and RM.

This step should be applied at all then?

I'm upgrading from 5.0.2 to 6.0.2 CLM
