Hi Hans,

Thank you for your reply.
Anyway, I tried to install Galaxy again by using the site "check-out" (hg clone 
https://...)  and it still cause problems.

Specifically, those were my steps:
1) I Installed galaxy in different location.
2) After run run.sh in the first time, I changed universe_wsgi.ini to listen on 
different port.
3) Manually, I copied "tools" and "tool-data" directories from the old instance 
of Galaxy to the new location (In order to get my new tools).
4) Also, I copied the old config tool file: " tool_conf.xml"
5) Then, Run the new Galaxy instance. In parallel, the old Galaxy is already 
"on line".

The problem is that any operation on the new Galaxy instance cause to the other 
Galaxy to
Throw the following error message:

I suppose that the problem is again caused due to collision between the 
But how can I separate between them? 

Thanks you!!

Hi Liram

I was suggesting: instead of copying the existing Galaxy directory into another 
location. Download and install a new Galaxy installation in a separate location 
on your file system.

for the installation procedure, see:


all you need to do in the new installation is changing the port number. 
It will create its own file system and by default it will use its own SQLite 
database. Hence, there should be no interference with your existing, production 
Galaxy installation.

Regards, Hans
