Looking for someone specialized on Presta Shop. I have a Presta Shop V1.1 and need to upgrade to V1.4
Back up all files on web site (Catalogue, clients, sales, Invoices, etc...)
Upgrade to latest version V1.4.
Restore all data into new version. (do the comparability test) to make sure is fully working.
That is It, for someone with experience in Presta Shop would be not so difficult.
