Hi Anshal,
#1 If you are looking to migrate on-prem PowerCenter, you can migrate this to an Azure VM.
#2 I don't believe there is a direct port for migrating all of your cloud ETL infrastructure, but I would recommend ensuring you are familiar with ETL tools within Azure.
I would first start off by looking into Azure Data Fundamentals for learning these types of tools. These types of tools include:
- Databricks
- Data Factory
- Data Lake Storage
Also, you would probably want to deploy this infrastructure with Azure DevOps and Terraform to save significant time (and if you are repeatedly doing this).
If this is helpful please accept answer.
