Migrating and upgradingYou can upgrade to the 2.0.0.0 version of HCL OneDB™ or migrate from other database servers to HCL OneDB™. Upgrading is an in-place migration method that uses your existing hardware and operating system software. Some changes to the HCL OneDB™ database server can affect upgrading from a previous release.
HCL OneDB™ Migration GuideThe HCL OneDB™ Migration Guide describes how to move data manually between databases, servers, and computers.
Migration of data between database servers
Migrating database servers to a new operating systemWhen you migrate to a new operating system, you must choose a tool for migrating your data, you might need to make some adjustments to your tables, and you must review environment-dependent configuration parameters and environment variables.
Adjusting database tables for file-system variationsFile system limitations vary between NFS and non-NFS file systems. You might need to break up large tables when you migrate to a new operating system.

Adjusting database tables for file-system variations

File system limitations vary between NFS and non-NFS file systems. You might need to break up large tables when you migrate to a new operating system.

For example, if you have a 3 GB table, but your operating system allows only 2 GB files, break up your table into separate files before you migrate. For more information, see your HCL OneDB™ Administrator's Guide.

The HCL OneDB storage space can reside on an NFS-mounted file system using regular operating-system files. For information about the NFS products you can use to NFS mount a storage space for the HCL OneDB database server, check product compatibility information.
