SaaS Modernization and Legacy Migration

Move a slow, fragile or inherited system onto something your team can change, in stages.

See What You Get

When every change takes longer than the last.

BitsSolved is a software studio in Tamil Nadu, India that modernizes slow or fragile SaaS products and migrates legacy software to a maintainable stack in stages, with the data migrated and tested before each cutover. Systems slow down the same ways: a database nobody dares touch, deploys that need a ritual, code inherited from a previous team. A rewrite from zero is rarely the answer. Moving in stages usually is.

Signs it is time

  • Recurring production incidents, slow pages or slow APIs
  • Deploys that are risky, manual or done by one person
  • A database that has become the bottleneck
  • Code inherited from a previous developer or agency
  • A platform, framework or server that is out of support
  • Infrastructure costs that keep rising

What the engagement includes.

  • An assessment first

    What the system does today, what is fragile, and the order of work that removes the most risk first.

  • A staged plan

    Small steps that each leave a working system, instead of one big switch-over.

  • Data migration with checks

    Scripts that move the data, with counts and spot checks that prove it arrived intact, rehearsed first.

  • Cutover with a rollback

    Each switch rehearsed on staging, with a tested way back.

  • Monitoring and documentation

    Alerts, backups and written notes your team can follow after the move.

The first call is free and is mostly us asking questions.

We can plan and review while your team does the work, do the work ourselves, or split it.

Case study: live at keynesta.com

A migration path designed in, not bolted on.

KeyNesta replaces other authenticator apps, so moving existing data across had to be part of the product from the start. The same applies to any system that replaces another.

  • One tap import

    Existing codes come across from Google Authenticator in a single import, rather than being re-enrolled one account at a time, which is the reason most people never move.

  • Plan the migration in

    A security product that cannot import from the one it replaces does not get adopted, however much better it is.

Rarely. A rewrite stops feature work and rediscovers every edge case the old system already handled. We recommend one only when the assessment shows staged change would cost more, with the reasons in writing.

The plan aims for none, and each cutover is rehearsed with a rollback ready. Where a short maintenance window cannot be avoided, you choose when it happens.

The migration is planned and rehearsed before anything moves, with checks that prove the data arrived intact. The original stays untouched until you sign off.

Yes. Moving off an old platform, framework, server or desktop tool is the same work: assess, stage, migrate the data and cut over with a way back.

Yes. We can plan and review while your developers do the work, do it ourselves, or split it between us.
