Hi Andrea,

Welcome to communities.

Current 7MTT 1.4 RC1 has the below limits

Please check this documentation link (section Requirements of Transition ) => https://library.netapp.com/ecm/ecm_get_file/ECMP1652695

Parameter Maximum limit

Number of controllers	4
Number of hosts	20

The following table lists the number of volumes in a subproject and the number of subprojects that can be run simultaneously during migration:

Parameter Maximum limit

Number of volumes in a subproject	160
Recommended limit for total number of volumes across all active subprojects in the web interface at any given time	240
Maximum number of active projects at any given time	8 (each project can have either a stand-alone subproject or a primary and a secondary subproject) Note: If you have eight active projects, you can replicate data from eight 7-Mode storage systems and their associated SnapMirror destinations.

Hope this helps
