Questions about Open Source vs Enterprise usage and migration

[jussara-ti]

Hello,

I would like to better understand the relationship between the Open Source and Enterprise editions of SeaweedFS.

We are planning to use SeaweedFS with more than 25 TB of storage. From what I understand, with the open-source edition I can use any amount of local disk space available, while the enterprise edition becomes a paid option starting at 25 TB.

1. Is my understanding correct that the open-source version has no technical limit on storage capacity (beyond hardware constraints), and that the 25 TB threshold only affects licensing for the Enterprise edition?

2. If in the future I decide to use the Enterprise edition only for part of my existing backups, how easy is the migration process from open-source to Enterprise for specific datasets?

3. Is it possible to:

   • Run both editions side by side (some backups on open-source, others on Enterprise), or
   • Run a single cluster that mixes open-source and Enterprise usage for different volumes/buckets?

Any guidance or best practices for this type of mixed or partial migration scenario would be very helpful. Thank you!

1. Correct.
2. Migration is 100% compatible.
3. Separate clusters are fine. Mixing up in one cluster is not possible. The binary is different.
