A couple of days ago a friend that is new to Magento reached out to me asking for some advice on how to update a Magento instance.He had inherited a legacy Magento project from another friend and now the merchant wants him to update the shop to a recent version of Magento.
Let’s take a look at what I am giving you in this document.If the extension needs to make any database changes, triggering the installation too early could cause it to miss some database changes and create errors which are difficult to fix later on. Upload the Extension and rewrite all files Extract the latest version ZIP-file (using Winzip, Win Rar, etc) and upload the app and skin folder to the root directory of the Magento installation.(You should not upload any other present folders within the supplied zip file, only these 2 directories). In this case it is clear that updated_at value will be changed only if value of any column is changed only in catalog_product_entity table but product entity contain multiple attribute values and updated_at need to be changed when any attribute value for product is changed on save.Updated at value is important for example in case that we want to check if product is updated and for example pull new data to third party application or something. Thanks Milos I will let @veloraven answer that question.In that case enter You can also upgrade Magento using our Installatron Script Installer if you have used it to install Magento.
It is advisable to only use this tool if you do not have addons like Themes, Modules, etc installed.
However if query set new value for SKU field My SQL automatically will set CURRENT_TIMESTAMP to updated_at field.
So this query will work: Conclusion is that fields which has DEFAULT value CURRENT_TIMESTAMP and "on update CURRENT_TIMESTAMP" definition should not be removed from $data array before save because values will not be updated.
The second way is to update from command-line or terminal. If you have sample data installed, your only option to update to 2.1.0 is through terminal.
I will be updating from Magento 2.0.2 to Magento 2.1.0 with and without sample data, because there is a slight difference in how Magento is updated. Only Enterprise edition with sample data can update to 2.1.0 through Web setup wizard. Enter the following into the terminal: Don’t do this immediately on live site, please test it first on dev environment.
If it has, it is vital to turn it off before installing an extension (or making any code changes).
