-To migrate in a parallel mode you just need to run several instances of the Ispirer SQLWays Wizard tool. For example, ​launching ​the first process of the Ispirer SQLWays Wizardspecify the set of objects that should be migrated during the first process. Then launch the same tool again and specify another set of objects or another database for conversion. ​And in the same way you can run as many processes as you need, but to do this, it's important to have powerful working environment to be able to run more than 5 processes of Ispirer SQLWays Wizard.+To migrate in a parallel mode you just need to run several instances of Ispirer SQLWays Wizard tool.
