Hi Rajesh,
Custom workflow models can be kept under /conf/global/settings/workflow/models/<My Project>/MyCustomWF directly by copying from older location to new one, see [0].
Locations - Workflow Models
Workflow models are stored in the repository according to type:
Out-of-the-box workflow designs are held under the following path:
/libs/settings/workflow/models/
Do not:
As any changes may be overwritten at upgrade or when installing hot-fixes, cumulative fix packs or service packs.
Custom workflow designs are held under:
/conf/global/settings/workflow/models/...
Runtime workflow designs (both out-of-the-box and custom) are held under the following path:
/var/workflow/models/
Legacy workflow designs (both design-time and runtime) are held under the following path:
/etc/workflow/models/
If these designs are edited using the AEM UI , then the details will be copied to the new locations.
Thanks,
Vaishali
