01 / Volume
Initial loads overrun the window
Sequential table copies struggle with large estates and put an unpredictable deadline on migration rehearsals.
Solution · Modernization
Migrate to cloud without a long cutover
Move large operational datasets with parallel snapshots, then keep source and cloud targets aligned with CDC until your applications are ready to switch.
- 01 Parallelize the initial snapshot
- 02 Apply changes continuously
- 03 Validate, switch, and retain control
The challenge
The copy is only the beginning
A migration must move historical volume quickly while continuing to capture every live change made during validation and cutover.
02 / Change
Production keeps moving
Rows continue to change while the baseline is copied, creating drift between source and destination.
03 / Cutover
Big-bang switches increase risk
Without a synchronized target, validation, rollback planning, and application cutover become tightly coupled.
How it works
Load once, synchronize until cutover
Gluesync combines snapshot acceleration and continuous CDC so teams can rehearse, validate, and switch on their schedule.
- 01
Baseline
Parallelize the initial snapshot
Split large tables into logical ranges and tune target concurrency to accelerate the first complete copy.
- 02
Catch up
Apply changes continuously
Capture transactions made during the snapshot and keep the cloud target current throughout testing.
- 03
Cut over
Validate, switch, and retain control
Monitor entity progress, coordinate the final handoff, and keep migration logic inside reusable pipelines.
Gluesync capabilities
Migration mechanics without custom glue code
Tune movement at the table, pipeline, and destination level while keeping deployment under your control.
01

02
Native bulk ingestion
Stage batches in the format and loading mechanism best suited to the target platform.
- Snowflake COPY INTO
- BigQuery load jobs
- SQL Server bulk copy
03
Hybrid deployment
Place agents close to source and target systems while Core Hub coordinates pipelines across network boundaries.

- Encrypted node communication
- Portable pipeline configuration
FAQ
Frequently asked questions
Answers about initial loads, continuous synchronization, cutover planning, and deployment control.
How does Gluesync reduce cloud migration downtime?
Gluesync loads the historical baseline first, then applies ongoing source changes through CDC so the cloud target can stay synchronized while teams validate and prepare the cutover.
Can large tables be migrated in parallel?
Yes. Logical partitioning and per-entity concurrency can split large snapshot reads and tune target writes to the capacity of each environment.
What happens to changes made during the initial snapshot?
The source agent captures changes made while the baseline is loading and applies them after the snapshot, keeping the target moving toward current source state.
Does a Gluesync cloud migration require a big-bang cutover?
No. Continuous synchronization lets teams rehearse, validate, and choose the final application cutover window instead of coupling the full data move to one outage.
