That's what I said, but it looks like thunderbird's quoting style made
that not very obvious. ;)

Re: [Trac] Consolidate two Trac in one Trac

[W. Martin Borgert]

Quoting Fayez Al Sedlah :

We have two trac that are using in two different places, we reach to the
point where we need to group them in one place but we don't want to loose
the data that already saved.  Noting that, they have two different
databases. I wonder the possibility of migrating all the data in one one
database? what should we take in account ?

Any hints will be appreciated.


I did exactly that a few days back :~) Went smooth.
Please look at the mailing list, subject "Merging two Trac instances?"
starting 2018-01-16.

Good luck!

[Trac] Re: Puzzling trac permissions error

[Niles Oien]

I'm embarrassed - it turned out that the system was running SElinux. 
Changing that resolved the issue. I had not heard of SElinux before, in 
fact when I saw it written I thought it referred to SuSE Enterprise linux.

The little WSGI test script I posted was pretty useful, I have to say, it 
was good to know what user was running the script and what their 
environment was. So I guess that is a contribution of sorts.

Thanks you all for all your suggestions,

Niles.

[Trac] Consolidate two Trac in one Trac

[Fayez Al Sedlah]

Hello guys, 


We have two trac that are using in two different places, we reach to the 
point where we need to group them in one place but we don't want to loose 
the data that already saved.  Noting that, they have two different 
databases. I wonder the possibility of migrating all the data in one one 
database? what should we take in account ? 

Any hints will be appreciated.

Thanks.
