Step 6: Migrating database:

(everything after step 6 is perfectly standard and normal)

[mengkuan1983]

does it mean i need to upgrade carbon ?

[snipe]

Should not need to upgrade Carbon, no.

Without more specific error messages from the 500 error, there isn't really a way for us to know what's happening here. Can you tell me what's in your storage/logs/laravel.log? Is it a web server level 500 or an application "whoops"-style error?
