Safely upgrade your PrestaShop 1.6/1.7 store to version 8 or 9

Still on PrestaShop 1.6 or an old 1.7? You're running unsupported code:
no security patches, PHP versions your host is about to drop, and
payment modules that will stop working. This offer gets you onto a
current, supported version — safely, and without gambling with your
live shop.

What this offer covers:
- Full staging clone of your shop — the entire upgrade is rehearsed
there, your live store keeps selling untouched
- Compatibility audit before anything is touched: theme, every
installed module, PHP version, database engine — you get a written
report of what upgrades cleanly, what needs work, what has to be
replaced
- The upgrade itself, executed step by step to the target version
(PrestaShop 8 or 9, your choice) with rollback ready at each stage
- Fixing the blockers that always show up: PHP session and CSRF errors,
Doctrine/DBAL incompatibilities, MySQL/MariaDB version mismatches,
deprecated overrides
- Core functionality tested on staging: catalogue, cart, checkout,
customer accounts, taxes, admin
- A clear go-live plan with realistic timing and a rollback procedure

What you receive: a working, fully upgraded copy of your store on
staging, plus the report — so you can see the result and decide on
go-live with real information instead of promises.

Go-live, module porting and theme work are available as add-ons below,
priced from the audit, so you never pay for work your shop doesn't need.

Scope note: this price covers a standard shop, one language/currency
setup and a reasonable module count. Very large catalogues, heavily
customised or multistore installs — message me first with your
PrestaShop version and a module list, and I'll quote before you buy.
I never touch a live store without a tested staging run.

I've upgraded PrestaShop shops of all sizes, including a high-volume
retailer with a B2B reseller area moving from 1.6 to PrestaShop 9.
