Обсуждение: [ADMIN] Oracle to Postgres conversion suggestions?

Hi,

I've been asked to help with one of these. I'm a bit wary, as I'm
thinking this is actually a really high risk endeavor. Any thoughts on
toolkits that might make this easy?


details:

- db size approx 5TB

- blob and (Oracle) spatial datatypes involved

- conversion and heterogeneous replication solutions needed


Currently looking at Amazon schema conversion/data migration services
but wondering if there are known good solutions out there!


Cheers


Mark

Do you look at ora2pg¹ ?

It's a good tool, that estimates the migration cost, migrate what it
can automatically (schema, constraints, data ) and let you do the hard
job : port your stored procedures and your applications if you didn't
use a good ORM.

Thanks - yes (briefly). While it looks good (and appears to be able to
do spatial data too)...the size of the source Oracle db means we need
replication ability to catchup the changes that were being made while
the migration was in progress.

In theory DMS can do this.
