Migration from Jmix 1.4.0 to Jmix 2.7.x - Tools and Process Guidance

Hi Jmix Team,

I am planning to migrate my project from Jmix 1.4.0 to the latest Jmix 2.7.x release.

Could you please advise on the following:

Automated migration tools: Is there any official migration tool, script, or utility available to automate or assist with this major version upgrade?

Recommended migration path: What is the step-by-step recommended approach for migrating from version 1.4.0 to 2.7.x? Are there intermediate versions I should upgrade through first?

Documentation references: Are there specific migration guides or documentation you recommend for this particular upgrade path?
