Hello -
My understanding is you should not run a new monetdb version with a dbfarm created from an older version. We have just updated our system from a Jul2015-SP3 version to the latest Jun2016-SP2 version.
I have created a new db farm and plan to recreate the tables in the new farm.
My question; How do you remove the old dbfarm? Our data is quite large (1.8 T) and I'd like to retrieve this space for other use. While I can start the db against the new farm, I can find no method of removing the old dbfarm to reclaim this space.
Thanks - Lynn
You can just delete the dbfarm directory.
So, are you re-creating your data instead of migrating data to new version?
I’m interested in how to upgrade to a new version without recreating the data.
Vince

Upgrade paths are automatic from the previous feature release, unless we have announced that a re-create is necessary due to internal changes that can not be handled automatically. Upgrades from bug-fix releases never require a database re-creation.
Upgrading over multiple feature releases, i.e. a very old dbfarm, is not supported. A dump and restore is the way to go.

To verify: You¹re saying my upgrade from Jul2015-SP3 to Jun2016-SP2 does not require a database recreation as the farm is not that old? This would be great.

Hi Lynn,
Like Soerjd mentioned previously you should upgrade in sequence so try not get behind in releases.
Also as I found out the hard way it's impossible to downgrade.
It plays havoc with your BBP version and catalog from memory.

I”m confused now. Our db has already been upgraded. We went directly from Jul2015-Sp3 to Jun2016-SP2. Was there a feature release in-between these 2? Am I ok using the same dbfarm for both these releases?
I will try to schedule upgrades as the fixes come out in the future.

Dear Lynn et al.
to summarise, unless stated differently in the respective release notes, MonetDB supports database upgrades from an older to a newer version in the following cases: - from a feature release or bugfix release to a newer bugfix release of the same feature release, e.g., from the Jul2015 feature release to its second bugfix release Jul2015-SP2; - from a feature release or bugfix release to the next feature release or one of its bugfix releases, e.g., from the Jul2015-SP3 bugfix release to the Jun2016 feature release or its Jun2016-SP2 bugfix release (as in your case).
We strong recommend, though, to backup your data/database(s) (i.e., dbfarm) before any upgrade.
We never support downgrades from a newer to any older version of MonetDB.
Feature releases are identified by a release name without "-SPx" (SP as in service pack) suffix, while the release name of bugfix releases has such suffix. Hence, between the Jul 2015-SP3 bugfix release and the Jun2016-SP2 bugfix release was the Jun2016 feature release.
And: "upgrading databases" refers to continuing using the same dbfarm (exclusively) with a newer version of MonetDB.
I hope, this helps to clarify.
Best, Stefan
