Hi there, for estimate the time of migration, please tell me how many products do you have.
Also on opencart 1.4 do you have some extra tabs or custom product attributes that needs to be migrated?
I think the entire migration process will take me around 4 hours if everything works how i expect.
few words about me:
I am an certified web programmer in HTML, CSS, PHP, MySQL and JavaScript. I also have very good knowledge of wordpress, opencart and phpbb. I have an experience of over 7 years, during which I worked for many web agencies. I am also certified by CISCO, on Network and servers administration running CISCO software and Linux ( RHEL/CentOS/Debian/Gentoo).
