Hi, I would like upgrade nop commerce from 3.4 to 4.3.
I already have all sql scripts for upgrade (not run yet)
Because of the diference structure  "no source x64" folder and "3.4 verson", I don know what I have to do exactly.
I already backuped db and all folder with files.
I have the link with help (bellow) but I can not find where is the information about: url eshop, connection string for DB, Main Icon for web etc...
https://docs.nopcommerce.com/en/installation-and-upgrading/upgrading-nopcommerce.html  

Could you help me  - step by step?
1) Backup Db and Files
2) Run sql script from 3.5 to version 4.3.... one by one
3) Create folder newWebsite
4) Copy all new files to this (newWebsite) folder
5) Insert file XY from
6) Modify file XY....

Thank you :-)

You may need need to take note of this step
(upgrading from 3.X to 4.X): If you want to upgrade from a version 3.90 to the latest version, you would need to install 4.00 first (over the existing database), run the 3.90 to 4.00 migration SQL script, and then upgrade to 4.10, 4.20 etc.
(dont know if it is needed if you are moving through to other versions) ?

1) Backup Db and Files
2) Run sql script from 3.5 to version 4.3.... one by one
Dont know if you really need to setup and run v4.0 website over the database as noted above ?
3) Create folder newWebsite4.4
4) Copy all new files to this (newWebsite) folder
This step does not mean copy all the files from v3.4
This is a fresh install of the v4.4 no-Source version
5) Insert file XY from
Are your images stored in the database ?
If yes then no need to copy the image files
6) Modify file XY....
I think you are best to do a complete install of v4.4 and create a new database and test out the site
Then later yopu can edit the App_data\dataSettings.json to point to the upgraded database

RE Pluigns: Do you have any third party plugins ?
Need to make sure all your plugins used are supported in v4.4

Anyway this is how I would do it - others may have different options
