Upgrade php from 5.6 to 7.1

To upgrade php version from 5.6 to 7,1 is enough that I switch it or I should change something into the code of suitecrm? Actually I am using the 7.8.3, planning this month to upgrade to 7.9.

upgrading from php 5.6 to 7.1 without change code, then I get error 500 on the login page. any ideas or help about it?

Upgrading PHP to 7.0 should work fine without any code change (as long as your SuiteCRM version is new enough, which it is).

However changing PHP sometimes exposes some quirks in your hosted system - they don’t all work the same. I’ll post in your other thread a few solutions to some errors you’re getting, and they might solve your 500 error.

Don’t upgrade to 7.9. yet, wait for 7.9.1 this Monday, and perhaps even for 7.9.2 a week later - many bugs are being solved.

thanks! on fastcomet with php 7.0 it works well!
Thanks I will follow your suggestion to wait some weeks to follow the next update.
