I need my live Odoo 15 Enterprise instance on [login to view URL] upgraded to version 19 while ensuring smooth operation. The core platform upgrade is straightforward; the main focus is on three custom modules that handle Australian phone-number formatting and phonebook sync, manage wholesale vs. retail price displays, and add weight calculations to paperwork. Since these modules have never undergone a major version upgrade, their data models and views require careful migration. Custom module details: Split one module into separate components: • A module for reformatting phone numbers to Australian international format (possibly native in v19) and syncing phonebook/call logs with our VOIP provider. • A pricing module with editable retail price lists for two zones (wholesale = retail – 10%), with the BAS report removed. Another module adds weight columns and a total weight field to quotes, invoices, and delivery dockets. Currently, version 15 contains some transactions but is mainly used as a contact database. It is not fully live due to accounting issues with parent-child invoicing, which appear resolved in version 17. Expected deliverables: An [login to view URL] staging branch running v19 with the full database restored. Refactored custom modules for v19, fully unit-tested, and deployed to the staging branch. End-to-end functional testing to confirm Sales & CRM flows, phone formatting, wholesale/retail price visibility, phonebook sync, and correct tax/account handling. A clean deployment plan with rollback capability for minimal downtime. Installation and testing of the AI Claude Connector (after stability is confirmed). Most of the upgrade effort will be on the custom apps. I previously attempted an automatic in-place upgrade, which worked except for the custom plugins. With new AI tools available, much of this work may be automated.

Hi, there. Upgrading your Odoo instance while ensuring the integrity of those custom modules is crucial, especially since they haven't been through a major version change before. The main risk lies in how the data models for your phone formatting and pricing modules will interact with v19's core changes. For instance, if the phone-number formatting is indeed covered natively in v19, we need to ensure that your existing functionality doesn’t conflict with the new implementation. This could lead to unexpected data handling issues during sync processes. I have successfully managed similar upgrades, focusing on custom modules where dependencies could break existing workflows. I can create a clear migration strategy that includes unit tests and rollback plans to minimize downtime. Would you like to discuss the specifics of the migration plan further? Best regards, Artem

Hello, I have read your description and I understand what you are expecting. 1. Will the system require integration with external services for phonebook syncing and VOIP provider interaction? 2. Should the pricing module in v19 support editable retail price lists for different zones with the ability to calculate wholesale prices accordingly? 3. Are there any specific requirements for the weight calculations and fields in quotes, invoices, and delivery dockets? I know very well that it is difficult for you to decide to post a job, because money is not water; it comes from your blood and effort. If a developer does not understand this and does not treat the project as his own, the project will not be successful. I can, and absolutely will, respect and value your investment, and I will do my best for this project. Best regards, Yurii
