UPDATE
I tried the provided solution but still I am unable to upgrade the SSIS packages using just config file so that brings me to next question.
Updated Question-
If I want to migrate SSIS packages,change in dtsconfig alone is enough or I need to use Data tool on packages itself? I am asked to upgrade using only config files which I believe is not possible.I searched on google and all I could find that I need SSDT to upgrade packages.
Kindly provide some insight on my understanding.
I have never worked on SSIS earlier and these days learning SSIS just because I am assigned a task of upgrading SSIS packages. I have around 17 packages for a particular project.
Thanks in advance.

Old Question:
Apologies as I can not provide much details as I do not have myself.I am asked to migrate SSIS package configuration from 2005 to SSIS 2017 and just given Config file for 2015 and nothing else. What all data I should be changing to make it 2017 compliant. Can someone suggest or pass Config file of those two version so that I can try to figure what changes are required.
Thanks
