Workflow Models in Common Repository Restructuring in AEM 6.4

Hi all,

I am trying to upgrade 6.2 to 6.4. As a part of Common Repository Restructuring in 6.4,  I have to move workflow models from '/etc/workflow/models'  to '/libs/settings/workflow/models' or '/conf/global/settings/workflow/models'  or '/var/workflow/models.'

Below is the steps: 

1. Deploy the modified Workflow Models into a local AEM 6.4 development instance, such that they exist in the Previous location.
2. Edit the Workflow Model using AEM's Workflow Model Editor at AEM > Tools > Workflow > Models.
3. When migrating modified AEM-provided Workflow Models
   1. With the Workflow Model Editor open, modify the browser's address URL, and replace the path segment /libs/settings/workflow/models with /etc/workflow/models.
      • For example, change: http://localhost:4502/editor.html/libs/settings/workflow/models/dam/update_asset.html to http://localhost:4502/editor.html/etc/workflow/models/dam/update_asset.htm

I am doubt where to change the browser's address URL. 

Please help me and guide.

Thanks.
