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
