* Request IDs with remote access permissions to the VM on your cloud or on-premises.
* Request necessary access to systems, applications, and data sources.
* Request VDI or VPN access for Data Storage Optimizer data engineers to enable remote access to the VM.
* Request a database user account (service account) or logins for connecting to the data sources.
* Make sure the database user account has read-only permissions for the database objects.
* Make sure that your system owner or Database Administrator (DBA) has copied or extracted any required data or files.
