Firebase Migration in Bristol
Firebase migrations for Bristol organisations, where getting data out in a usable form is its own project. The managed export produces a format only Firestore can import, so moving anywhere else means writing something that reads every document and converts it — work that surprises teams who assumed an export button existed.
Why this comes up
The problem
The export completed successfully and produced files nothing outside Firestore can read.
What you get
What we deliver
- Extraction written against the API where the destination is not another Firestore
- Document shapes profiled, since collections hold several generations of structure
- Subcollections handled explicitly, as these do not appear in a naive export
- Authentication users exported with hashes where the destination can accept them
- Storage objects and their access rules transferred separately from the database
- Read cost accounted for, because extracting everything is billed per document

Firebase Migration in Bristol — common questions
- Why is the export not usable?
- Because it is designed for restoring into Firestore rather than for portability. The files are in an internal format, so any destination other than another Firestore project needs a custom extraction that reads documents through the API and writes them out.
- What about subcollections?
- They need traversing deliberately. A subcollection under a document is not returned by listing the parent collection, so an extraction that iterates top-level collections silently omits an entire layer of data — frequently the layer holding the detail.
- Does extraction cost money?
- Yes, per document read. Pulling a large database out is a substantial number of reads charged at the normal rate, which is worth estimating before starting rather than discovering as an unexpected line on the month you migrated.
- Can users move without resetting passwords?
- Often, if the destination accepts the hash format. Firebase can export password hashes with their parameters, and a destination able to verify them avoids forcing every customer to reset — worth establishing early, because that reset costs active users.
- Do you work with businesses across Bristol?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South West, including Bristol and the surrounding Bristol area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Bristol businesses do you usually work with?
- Engineering-grade requirements from aerospace clients, and brand-led digital work from the creative and environmental sectors. Beyond that we work across Aerospace, Creative & Media, Technology, Financial Services and Environmental.
- Do you cover the areas around Bristol?
- Yes — we work throughout South West, including Cardiff, Bath, Southampton. Bristol is an urban area of roughly 700,000+, and we take on work across the wider Bristol region rather than the city boundary alone.
