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.

If you are using the same version of ISM, copy the same sm_versions file from your old database server to the new database server installation.

If you are using other storage managers, copy your previous sm_versions file from the old $INFORMIXDIR/etc directory to the new $INFORMIXDIR/etc directory.

If you are migrating from Version 7.31 or moving data from that version to the current version, unload the contents of the sysutils:bar_version table.
