Major Version Upgradation from 9.4 to 9.6

[Quipment Logo]

Hello,

We have a windows setup for PostgreSQL(Version 9.4).

Now we are upgrading Major version 9.4 to 9.6.

Total Database size - 421 GB
RAM - 16 GB
Core - 8
Size of Data Directory Drive - 500 GB

We have 3 database in 421 GB.

1) X database size - 12 GB

2) Y database size - 1 GB

3) Z database size - 408 GB

Now when we start pg_upgrade command it is started and also generating dumps but it is stuck when it is creating large database (408 GB size).

we have kept running pg_upgrade for 24 hr but it is not going further from creating large database dump.

Is it space related issue or something else? How can we deal with this Problem ?

Thanks,

Amee Sankhesara
