Salesforce development company.<\/a> Development timelines compress by roughly half once teams shift from custom code to Lightning’s declarative tools.<\/p>\n![\"Salesforce](\"https:\/\/www.flexsin.com\/blog\/wp-content\/uploads\/2026\/07\/image290.png\")

The Salesforce Lightning Migration Process Explained <\/h2>\n
Discovery comes first. Teams run the Lightning Readiness Check against the existing org, inventory every custom field, Visualforce\u202fpage and integration, and capture baseline metrics – case resolution time, sales cycle length, login frequency – so the results are measurable later. Skipping this step is the single most common reason migrations run over budget.\u202f <\/p>\n
Build and validate comes next, and it’s the longest stretch. Custom pages get rebuilt as Lightning components. Visualforce gets refactored into Lightning Web Components wherever it still matters. Integrations get retested against the new UI, and power users validate functionality inside a sandbox before anyone outside IT sees it.\u202f <\/p>\n
Rollout and stabilization close the process. Administrators and internal champions switch first, then the rest of the organization follows in waves, backed by role-specific training. Classic access typically stays available for a short overlap window, which lowers resistance without slowing adoption. Most mid-sized organizations complete the full sequence in six to eight weeks; heavier customization can stretch that timeline into a\u202fquarter.\u202f <\/p>\n
Common Salesforce Lightning Migration Challenges <\/h2>\n
Most failed migrations don’t fail on technology. They fail on assumptions. Teams assume every custom button and Visualforce page will carry over cleanly, then discover mid-project that a third of their AppExchange apps need compatibility patches before they’ll run on Lightning. Teams assume users will adapt on their own, skip role-specific training, and end up with a support queue full of “where did this feature go” tickets in week one. <\/p>\n
Teams assume the readiness assessment is optional because the org “isn’t that complicated,” then spend the back half of the project untangling dependencies that a two-day audit would have surfaced up front. None of these are technology failures. They’re planning failures, and every one of them is preventable with the right sequencing.\u202f <\/p>\n
Key Indicators Your Business Is Ready for Lightning <\/h2>\n
Not every org should migrate this month, and forcing the timing usually backfires. Three signals tend to line up when the moment is right: the business isn’t mid-way through a peak sales cycle or major launch, the customization footprint and AppExchange dependencies are documented rather than assumed, and there’s an executive sponsor willing to own the change instead of delegating it entirely to IT. <\/p>\n
