Some information on classic vs. advanced policies and expressions with NetScaler ADC 12.0.
In the process of a NetScaler ADC configuration, NSOS 12.0 may present a message to you, stating classic policies and expressions are deprecated. So you should use advanced policies / expressions. So far, so good. But as there are some functionalities which DO NOT support advanced policies and expressions yet, this is confusing. Next, Citrix is planning to remove classical policy / expression support (which are replaced by advanced policies and expressions now) with some NSOS release in Q2/2019. Therefore, we need to move to advanced policies and expressions instead, learning how to put the puzzle together … ;- /
Citrix provides some further information helping us on this:
- NetScaler Deprecated Classic Policy Based Features and Functionalities FAQs, see CTX234821, and
- the nspepi policy / expression conversion tool, see NSOS 12.0 eDocs.
Will definitely have a look into the latter – nspepi. So stay tuned.
