Migrating from Talend’s jobs to Databricks requires rebuilding ETL logic using Spark. There is no native one-click converter provided by Databricks, so the typical approach is to audit and refactor each Talend job into code (PySpark or Spark SQL) in Databricks notebooks or scripts.

In terms of accelerators,  this blog may be of some help.

Also, saw someone providing a tools based migration service but use your discretion to engage with them - I haven't had any interaction with this service provider so can't endorse them.
