I have a question, currently i have a setup of 8 servers with 30+ database each database having 10 schemas each server has 64 core 16 GB RHEL with Postgresql 9.6 Enterprise edition. There are around 40-50 crore records from all databases. There are about 20000 users who access the 30 databases with access only to 1 database for each user

We want to migrate to single server, so the question is

1. Can we migrate to single server (considering the volume and no of databases (30+) to single database and 300+ schemas in the single database
2. What should be the Configuration of this single server (earlier each of the 8 server had 64 Core 16 GB) on RHEL 7.x
3. Should we keep single database with 300 schema or 30 databases with 10 schema in each database
4. Should the server be physical or VM and can 1 server tolerate the load of 20000 total users out of which 7000-8000 users are concurrent

Please advice
Thanks
