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?
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.
Anyway, I installed nop 4040 and tried to upgrade 4.30 t0 4.40 but received the following error:
Sequence contains more than one element
What does this mean?
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:
