Data volume is the total size of data transferred during migration. For databases, this includes tables, indexes, and schema. For apps, it includes code, assets, and environment data. We measure uncompressed data size - you only pay for what you actually migrate.
We support PostgreSQL, MySQL, MariaDB, MongoDB, Redis, and MinIO (S3-compatible storage). Cross-database migrations (e.g., MySQL to PostgreSQL) are available on all paid plans with automatic schema conversion.
Cross-provider migrations allow you to move your entire infrastructure between cloud providers (AWS → GCP, Azure → AWS, etc.). This includes databases, storage, applications, and configurations. This feature is exclusively available on the Enterprise plan because it requires specialized tooling, provider-specific expertise, and dedicated support to ensure zero-downtime migrations across different cloud platforms. Contact sales to discuss your multi-cloud migration needs.
CDC enables zero-downtime migrations by continuously replicating changes from source to destination. The initial snapshot is transferred, then ongoing changes are streamed in real-time until cutover. Available on Pro and Enterprise plans.
Speed depends on: bandwidth tier (10-200+ Mbps), parallel streams (1-unlimited based on plan), source/destination network capacity, and geographic distance. Pro plan offers 200 Mbps with 5 parallel streams. Enterprise gets dedicated 1 Gbps+ bandwidth.
Yes! The Free tier includes 10GB of data transfer and 3 migrations per month. Perfect for testing small databases or trying Docka before committing. All paid plans include a 7-day free trial with full features.
No. You're only charged for successful, completed migrations. If a migration fails or is cancelled before completion, no data transfer fees apply. Your included GB quota is not affected by failed attempts.
Cloud providers may charge egress fees for data leaving their network. Docka pricing is separate from these fees. Enterprise plans include options for private network peering to minimize or eliminate egress costs.
Yes! Enterprise plans offer volume discounts for large migrations (1TB+). Contact sales for custom pricing on terabyte-scale migrations, dedicated bandwidth, and multi-region deployments.
