I will migrate your opencart 3 store to opencart 4 and fix broken modules
Ahnaf Shoumik
About this gig
OpenCart 4 changed enough under the hood that most OpenCart 3 extensions simply stop working - stricter typing, a reworked extension structure, and altered controller and model conventions. If your migration broke your modules, or you have been putting the upgrade off because you know it will, that is what this gig is for.
What I do:
- Full OpenCart 3 to 4 migration with data, orders and customers intact
- - Repair third-party and custom modules broken by OC4's architectural changes
- - Port custom modules, event and hook extensions, and template overrides
- - Rebuild theme customisations against the new structure
- - Re-verify payment and shipping gateways after the move
- - Staging deployment first, so your live store is never the test
I have 5+ years on heavily customised OpenCart 3 and 4 storefronts and I administer the Linux servers they run on, so server-side issues during migration do not need a second vendor.
Message me with your store URL, OpenCart version and a list of installed extensions, and I will tell you honestly what the migration involves before you order.

FAQ
Will I lose my products, orders or customers?
No. Data migration is part of every package and I work on staging first.
What if a module cannot be ported?
Some abandoned extensions have no OC4 path. I tell you before you order and quote a custom rebuild separately.
Do you handle the server too?
Yes. PHP version, Nginx or Apache config, SSL and permissions are included.
Can you work on my live store?
I build and test on staging, then deploy during a window you choose. Your live store stays up throughout.
