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.
Ensuring the successful creation of system databasesThe first time the database server is brought online, the sysmaster, sysutils, sysuser, and sysadmin databases are built. After moving to a database server on a different operating system, check the message log to ensure that the sysmaster and sysutils databases have been created successfully before you allow users to access the database server.

The first time the database server is brought online, the sysmaster, sysutils, sysuser, and sysadmin databases are built. After moving to a database server on a different operating system, check the message log to ensure that the sysmaster and sysutils databases have been created successfully before you allow users to access the database server.

After you ensure that client users can access data on the database server, the migration process is complete.
