I’m trying to upgrade an existing local site from 8.5.6 to 9.0.0 to try the new release and assess how easy the upgrade process is (I work for a web agency and we are considering upgrading our client’s sites to v9).
I tried to upgrade using the web interface (following this guide: How to Upgrade Concrete5) but it failed silently. I also tried to replace the concrete/ folder with the one from the v9 and running concrete5 c5:update.
No luck so far, can anyone direct me to a guide or give me advice?
