ePO: new installation to existing (empty) database

Is it possible to use an already existing database while doing a fresh install of ePO? The installer detects the existing database and only offers to delete the database ... Are there some command line options to override this behaviour? Thanks for any help.

Re: ePO: new installation to existing (empty) database

Hello @User36779936 ,

For using existing database to fresh version of EPO, you have to make sure you are using same version of Epo which was previously used with that database.

Most Imp: That database should have epo server snapshot stored in it. Follow below kb for same.

Kb66616

IF you planned to use higher version of epo with old database. It will not work as expected.

Re: ePO: new installation to existing (empty) database

Thanks for your answer. Sorry I was unclear with my question: I do not want to recover from a snapshat.

I just want to re-use an empty but already existing database ...

I'd like the installer to just skip the creation of the database ... and continue with creating the required tables.

Is that possible?

Kind regards
Markus

Hello @User36779936 ,

*YES IT IS POSSIBLE*

I would like to thank you for this query, I have replicated this scenario in my environment and it works fine with EPO 5.9 and 5.10.

Steps to proceed:

1. Create a Blank database > The credentials from which you created should have Public or Dbcreator. from KB75766

2. Run installation of EPO fresh > skip restore part > while installation it will ask for database credentials> select the server on which your blank database is located> provide exact name of your blank database.

3. proceed with the installation it will work fine.

From my experience, default database ePO creates will be ePO_<machine name>. If you have created Empty database and wanted to install ePO then it should be good.

@User36779936 ,

One more thing which is important here, when you are trying the installation with EPO 5.10 . Make sure you are creating two databases , eg;

1. Test

2. Test_Events

Test is the primary database and Test_Events is the events database, In place of test you can use any name.
