Hi, Upgrading Magento from 2.3.5 to 2.4.8 is a critical move to future-proof your store, and I understand the balance needed between technical precision and maintaining your current custom functionality. I have extensive experience with Magento 2 upgrades, including data backup, staging site deployment, and extension compatibility assessments. I will ensure the Mageplaza extensions and other plugins, including Stripe and PayPal integrations, are all fully functional post-upgrade, and I'll handle your nuanced product page customizations with care, such as disabling specific options, adjusting rounding logic for quantities, and preserving conditional fee calculations. I’ve shared an initial estimate based on your detailed description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. My approach includes thorough staging site testing to guarantee your live site operates flawlessly after deployment. Looking at the scope, a realistic timeline would be approximately 14 days to cover backup, upgrade, extensions update, custom functionality adjustments, testing, and final deployment. Could you clarify whether you have customized any of the Mageplaza extensions beyond their default setup, or are they stock installs? Best regards, Asad

Hi, I will upgrade your store from 2.3.5 to 2.4.8 on staging first, update all Mageplaza extensions, install latest Stripe and PayPal plugins, and handle the product page changes including disabling Order Extra M2 and Wastage fields and enforcing whole-number pack quantities with rounding. The 2.3.5 to 2.4.8 jump requires migrating catalog search from MySQL to Elasticsearch, a breaking change needing correct server setup before the upgrade runs. I will configure that along with Composer so future patches apply cleanly. Full functionality testing before going live. Questions: 1) What hosting setup are you on (dedicated, VPS, or managed)? 2) Is the split carte processing fee handled by a custom module or the theme? Happy to walk through the approach in more detail. Kamran

This is a significant upgrade that involves transitioning from an older PHP environment to the latest architecture required by Magento 2.4.8. I will handle the process in two phases to ensure stability: first, a staging migration from 2.3.5 to a stable 2.4.x branch, followed by the final upgrade to 2.4.8. Since most of your existing extensions and your current theme will likely be incompatible with the latest version, I will prioritize installing the latest compatible versions or alternatives where possible. I will specifically focus on the latest Stripe and PayPal integrations to ensure secure payment capture, and I will manually update the custom code for the Postcode Lookup and Delivery Calendar extensions to ensure they function correctly with the new Magento core. I will implement the custom rounding logic to ensure "Order Pack Quantities" always round up to the nearest whole number and configure the split-pack processing fee logic to remain functional for future use. I will also disable the specific attributes and UI elements as highlighted in your brief to streamline the product pages. The upgrade of the core system is relatively fast, but the majority of the timeline will be dedicated to refactoring extension code, updating the theme, and performing the exhaustive 16-point testing checklist you provided. I estimate a timeline of approximately 20 days (+/-) to ensure a bug-free deployment from the staging environment to your live site.

@usamae

Hey, the 2.3.5 to 2.4.8 jump is a big one - primarily because 2.4.x dropped MySQL search and now requires OpenSearch/Elasticsearch. I've done several of these and the Mageplaza extensions you listed (SMTP, Better Blog, Banner Slider, etc.) usually need fresh installs rather than in-place upgrades, so I'll handle that properly. My approach: clone to a dev/staging environment first, run the full upgrade there, get all extensions working and tested, then deploy to live only when everything checks out. I'll also handle the functionality changes - disabling Order Extra M2/Wastage 10% across those categories, the decimal prevention on pack quantity, and making sure the split cart fee logic stays intact for future use. Payment gateways (Stripe + PayPal) will be tested against 2.4.8 compatible versions before going live. Whats your timeline looking like? - Usama

Hello, I have extensive experience upgrading Magento from 2.3.x to 2.4.x, including full Composer migration, extension compatibility resolution, payment reconfiguration, and staged deployment. I will create a complete backup, clone to a secure staging environment, upgrade to 2.4.8, update incompatible Mageplaza extensions, install required plugins, and ensure Stripe and PayPal function correctly with proper capture and email workflows. I clearly understand the functional changes: disabling “Order Extra M2” and “Wastage 10%” across all products (including out-of-stock), restricting product page elements to “Ordered” only, preserving split pack fee logic (£24), enforcing pack quantity rounding to whole numbers, validating postcode delivery logic, calendar restriction to 5th working day, discount codes, cart calculator, and full checkout validation. Timeline: 10–14 days total (3–4 days staging setup + upgrade, 3–5 days extension fixes & custom logic, 3–5 days full regression testing before live deployment). Full system testing checklist will be documented before go-live. Thanks, Asif
