Because it’s very difficult to take exams at PearsonVUE right now, you may get in trouble regarding the timely recertification of existing certifications. Therefore some vendors have announced an extension for their recertification expiration:
PaloAltoNetworks is extending the certification expiration date by six month for Credential holders with expiration date between March 1, 2020 and July 31, 2020.
Fortinet is extending the certification expiration by one month so far. We assume that this extension will be extended again :-).
Update March 27th: Fortinet will extend the expiry dates of all existing NSE certifications by 6 months as of March 16th 2020 (the date of PV’s test center closures).
Due to several known issues, we did not recommend the use of FortiOS 6.2 in productive environments for the first couple of months.
As per FortiOS 6.2.5, we noticed that most of the issues have been resolved. Please have a look into our FortiOS upgrade guide for the upgrade procedure.
