Hi,

Due to incompatibility in new PHP version, I need to upgrade zencart version 1.3.6 to latest 1.5.1. Please let me know:

- Is this feasible?
- What document should i be referring?
- Other than backup of website and database, what should i have to take care?
- Solving incompatibility modules?
- Migrating templates, products, orders, etc?


Any help will be really appreciated. Thanks

Regards,
Chintan.
