Frequently Asked Questions
Everything you need to know about our Migrations & Upgrades services.
Q.How quickly can we start on this Migrations & Upgrades project?
We begin with an immediate technical discovery within 24 hours. Emergency engineering fixes are prioritized immediately, while complete projects begin with scoping and architecture design within 2-3 business days.
Q.Do we get 100% ownership of the source code and intellectual property?
Yes, absolutely. Upon completion, 100% of all intellectual property, git repositories, documentation, and cloud architecture access are transferred directly to your organization.
Q.Will there be any downtime for our live users during updates or deployment?
No. We utilize zero-downtime deployment pipelines, blue-green deployment strategies, and staging environments to test changes thoroughly before cutting over seamlessly to production.
Q.What post-launch technical support and maintenance options do you offer?
Every project includes a 30-day post-launch warranty with dedicated bug fixes and performance monitoring. We also provide ongoing SLA-backed maintenance plans for continuous support.
