Thanks for getting in touch! Unfortunately, there is no way
directly in Octopus to help you with your SSIS deployments.
However, I think I have just the thing to help you out here.
Octopus has a community library for step templates that cover a
wide range of needs. The link is below. https://library.octopusdeploy.com/step-templates
I had a quick search and found the following step template.
I’m not 100% sure how useful this is for your scenario but
hopefully it is what you are after.
