We recommend you to duplicate your live store on a development store and try installation on it in advance.

Backup magento files and the store database.

It’s very important to backup all of themes and extensions in Magento before installation, especially when you are working on a live server. We strongly recommend you to do not omit this step.

Disable all cache related section that you have in your magento.

Upload the theme files.(refer Next Part Theme Files Upload)

Active Netbase Extensions, open command line in folder root of magento and run commands via ssh using putty or others, php bin/magento setup:upgrade.

Sometimes your site is broken, after run this command, it’s because of you ran this command with the incorrect user. If your site was broken, it’s very important to set the file’s permissions and ownership correctly, after run this command line. You can refer this command chown -R <owner>:<group> <magento root directory path>.

 Select “Netbase Multistore” theme in Stores > Configuration > General > Design > Design Theme > Design Theme for Magento 2.0.x version, and select “Netbase Multistore” theme in Content > Design > Configuration page for Magento 2.1.1 version.
