Two Tomcat instances on same Unix Server

Question

We are planning for JIRA 4.2 to 5.2 upgrade.

Once the compability Check is done successfully we will stop 4.24 and start using only 5.2.

Until that we prefer to have 2 diff database instances each one pointing to 4.2 and 5.2 respectively.

Created  a separate folder in the Unix server for JIRA 5 ,pointing to a different DB which has the copy of 4.24 data ,created new jira_home etc.

Can you please suggest if it is  possible to have 2 tomcat (JIRA) instance on the same unix server parallely running(However pointing to diiferent DB ).?

Yes, as it sounds like you have separated everything completely, there's no harm (other than load on the server) in running two Tomcats running two separate Jiras.

Bear in mind though - if your users continue using 4.2, they will be updating the 4.2 instance, and just swinging over to the 5.2 later will lose all the data - you'll need to plan for data migration (or throw away the test 5.2 and re-upgrade the data)
