Looking at KB76736 - 'ePO 5.0 supported products'
It shows that EPOAMT 188.8.131.527 is the minimum supported version under ePO 5.x so I suspect that's just not going to work. (i.e. DC 2.0 minimum required with ePO 5.x)
Can you share the KB number you're referring to please ?
Please bear in mind this is more a point-product question than ePO and may need moving to the EEPC group for further advice.
EPO 5.0 requires Deep Command 2.0. Deep Command 1.5 is not compatible with EPO 5.0.
