Hey @Mansor2 ,
please note that I am not part of ServiceNow and especially not part of the account team of this customer so that I cannot give any binding advice at this point.
All I can say is that for most of the customers agile development needs to be part of their order form so that they are eligable to activate the corresponding plugins. If so, they can still activate the plugins while they are on Zurich. 
This means that they should check their order form or reach out to their individual ServiceNow Account Executive to clarify.

Hope that helps!

Cheers
Oli
