Hi, Technoteca. I am Alek and I have a question about upgrade curently 2.5.1 to 3.1. So, Im on Ubuntu Server 17.10 tomcat 8 postgres 9.6. system. Is there in any manual step by step guide? I read tehnical manual but there is no clearly enough guide. So I tried couple of time to do update but with no succses. What Im doing - stop tomcat, remove cmbuild folder and war file, upload new one war, start tomcat. This war enough when make previous updates.
When I used to make v. 2 updates, a gui interface similar to Linux always came out after the upload of the war file in browser. So i want to move to new interface and version but I dont know how. Please make some guide step by step here in this tread or even better in tehnical manual. Thanks in advance
I have created my own setup guide based on some research, trial and error. I set up a new server with CMDBuild 3.1 and moved the database over.
It’s quite easy to configure CMDBuild manually when you know how. Basically you just have to change the database.conf-file and put it in //conf/ where is the same name as the cmdbuild folder in webapps as described in webapps//WEB-INF/README.txt.
CMDBuild takes care of the database upgrade when you open it the first time. If you get any errors along the way, just check the log file (e.g. /var/log/tomcat8/cmdbuild.log).
I’ve translated what I’ve done so far from norwegian and put it here:

Any suggestions would be appreciated.
Hi, audun.wangen1. I want to thank for all of your help here. I have a simple question if you can help I’ll be gratefull. So - where I have to put database.conf file exactly? Now my config is as follow:
database.conf is in /webapps/cmdbuild/WEB-INF/conf.
I have a copy in /var/lib/tomcat8/webapps/conf.
When I start browser on adress h t t p://x.x.x.x:8080/cmdbuild the browser redirects me to adress h t t p://x.x.x.x:8080/cmdbuild/ui/#login where nothing happend (please see uploaded file). 
Maybe my conf file is not OK. I have a 3 row in it
db.url=jdbc:postgresql://localhost:5432/cmdbuild
db.username=myusername
db.password=mypassword
I think that conection betwen db and webapp not working. I try to reboot server, to start and stop cmdbuild trought Tomcat Web Application Manager - no success
Because of upgrades and security, your should put database.conf in /var/lib/tomcat8/conf/cmdbuild/. Then you can delete the conf-file in /webapps/cmdbuild/WEB-INF/conf/.
If it still doesn’t work, check /var/log/tomcat8/cmdbuild.log for errors and post them here, and I’ll try to help you figure it out.
Dear Audin, thank you for all your help! Everything is UP and operational thanks to you! Cheers from Bulgaria!
best regards Alek!
