Routing issue(?) when I upgrade ghost from v5 to v6

Hello, I am helping our mkt team to evaluate the ghost 6. our current company site is hosted by ghost on v5.

so I installed ghost 6 locally and run just fine. then I exported the files, got the images from ghost support team, and export the routing files too. added to local installation and the site works fine mostly.

on our prod site, both links below work.

and “industries” is a tag as in the ghost admin panel.

my-prod-site-domain/industries/csp/
my-prod-site-domain/csp/

but on my local setup, the one with tag does not work
my-local-ip/industries/csp/ => 404 not found
my-local-ip/csp/ => works

Yet in my local setup, the “industries” is show in the tag list with correct count of # posts.

I also downloaded and added the routing.yaml file too. but did not help.

So what could be missing?

turns out, I have to use the import routes feature under Labs to do the importing.

I previous copy/pasted the routing file on the server and restarted the server but did not activate the routing.

Though theme files can be copied and worked fine.
