Postgres Migration from Postgres 9.0 on Windows to Postgres 10.0 on Linux
Hi,
I’ve been tasked with migrating our production database from Postgres 9.0 on Windows to Postgres 10.0 on Linux. I’ve used pg_dump and pg_restore and it works fine but the time taken for my dry run of the migration is about 12 hours (8 hours backup and 4 hours restore)
What can I do to reduce the migration time so that I can get production up and running again as soon as possible? I have the option to upgrade either machine if that helps and in that case what would help most faster disk IOPS? RAM? CPU?
