based on my analysis, if your wes expired after 5 years you have to apply freshly or start again.

Caution to every one. I went the "Duplicate Evaluation Report" route, submitted my express entry profile, and got an invite. After submitting my PR application and waiting for around 2 months, my application got "Cancelled as Incomplete". The reason being the older than 5 years evaluation report. My duplicate report had the current date but also mentioned when actual evaluation was done, which was more than 5 years ago. Therefore, I can confirm that validity does NOT extend with a duplicate report
Brutal lie /Unawareness of WES customer care.
So order for upgrading your ECA, or renewal of ECA, or duplicate evaluation report, would actually end to the same print out.. will be given with new date, ie current date but along with tag line stamped with duplicate report from actual report done on 5 years date.
But wes customer care agents are forced to lie or unaware of the printouts and blindly reply the template answer, Wes work closly with ircc that u will get a new date and no need to do apply freshly, , but in printout new date will be given with keyword duplicate from actual dates. Which lead to rejection.
WES lie, template answer:
Adding new credential = Upgrading your ECA. Upgrading would result in issuance in new ECA report, you won't need to go for renewal.
as i posted few years back, i dint got much reply, one person said he has got approved, but 3 people has said they got rejected in this year and late 2018.
Moral of the story..
Brutal lie of WES leads to one month delay = hamper another 1 year.
