I will upgrade your Opencart store version 1.5.x or 2.x to latest Opencart version. The standard upgrade procedure is described below I will backup your database and existing files just in case. Themes : I will deliver job with Opencart default theme. Because your current theme won't work on newer version of Opencart. I can install new theme if you provide me that as compatible with new opencart after upgrade. I highly recommend Journal 3 theme. Module Positions : Any core modules should retain their position. 3rd party modules will be removed. They will need to be customized over again.
