Nimbostratusupgrade our F5 units to 12.0 from 11.6 EHF5 (EHF-x).
Does existing iRules work at 12.0 ? or conversion of iRules is required from existing to (java node.js) format ? if yes then do we need separate license ?
EmployeeiRules is and remains a Tcl dialect language, so your rules from 11.6 should work fine under 12.0 without modification. There are no plans to eliminate, deprecate or replaces Tcl-dialect iRules. It will be supplemented by iRulesLX, but as I say, iRulesLX does not replace iRules. In 12.0, iRulesLX is Early Access, so at this point, there is no public facing documentation. See this solution article:
