Downgrading from 13.5

[Uffe]

Hi all,


After our recent upgrade from 11.1 to 13.5, we've noticed multiple issues with document generation and database modelling, where things that worked in the older version no longer do in the new. We're getting nothing back from Sparx support, so we're going to have to look at downgrading.

We've upgraded all our databases (SQL Server) to the 1220 version of the schema. This means downgrading to 12.1 should be OK, but I'm thinking about what we'll need to do if it turns out the bugs that are causing our problems were already present in 12.1, meaning we'll have do go even further back to either 12.0 or 11.1, where we know things work.

Does anyone have experience of downgrading past a schema change?

Or is it possible to run 11.1/12.0 on a 1220 schema?

Thanks,

Hi Uffe,
We currently stick on 1310, due to trouble we had with V13.5.

Maybe V13 suites to you.

However, I remember that I had to do some small adoption on document templates as well.

I have no experience with downgrading, but from what I read about upgrading it was always said that working with old/new version in parallel was almost never an issue (as long as you did not use new features). So basically you should just be able to replace the clients with the old version. At least give it a try with a single one and then go on depending on results.

Uffe, the schema upgrades will work with practically any version of EA.
