Running 2 versions of GnuCash

[Nikos Charonitakis]

Hello all
For testing reasons i want to run 2.7.3 I compiled and install it in
my fedora 27 laptop where i regularly use the stable version. I
installed 2.7.3 in my home directory ~/gnucash/unstable  but I
hesitate to run it, i am afraid messing anything with my stable
version (.gnucash in home dir). So what to do? run it? anything to
watch?

Thanks in advance
Nikos
