Upgrading from 4.20 to 4.50

3 mesi tempo fa
Hello Andrei,
I'm trying to upgrade to 4.50 but there's a problem.
From 4.20 to 4.30 there's the update.sql and that's fine, but next step (4.30 to 4.50) fails because database has not been updated to 4.40.
Is there an update.sql from 4.30 to 4.40 or I have to install (!!!) 4.40 just to update db?

Hi, just install 4.40.x should work fine.

Just do the sql upgrade for 4.30 and then install 4.50 version, that will do it, there is no need for 4.40 installation :-)

No, it doesn't work. Reading the error log there are missing elents created on 4.40 reqyured for db uograde. It seems necessary 4.40, but i don't understand why instead of one minute sql script it is necessary losing hours fir a useless 4.40 installation.

Sequence contains more than one element

What does this mean?

This exception is caused by trying to install to a database that has already been installed (i.e. already has tables). are you using existing db connection to your app settings?

I am trying to upgrade also from 4.2 to 4.5. Can you go stead ahead from 4.2 to 4.5 without SQL script?
After I have copied all file I get the message:
HTTP Error 500.30 - ASP.NET Core app failed to start
Common solutions to this issue:
The app failed to start
The app started but then stopped
The app started but threw an exception during startup
Troubleshooting steps:
Check the system event log for error messages
Enable logging the application process' stdout messages
Attach a debugger to the application process and inspect

Can someone help me to solve the issue?

You still need to upgrade the DB from 4.20 to 4.30

nopCommerce_4.30_UpgradeScripts.zip

The error "ASP.NET Core app failed to start" implies you need to install .NET Core runtime
