Dependency Issue with migrating from 6.6 to 7

[vjpiyush]

We are currently using CentOS 6.6 and upgrading to CentOS 7 , we are using lot of 3rd party open source, we are facing major issues in python packages, we are using python-pika , python-sqlite2 ,python-webpy etc all those have the dependency on python 2.6 with centos 7 python 2.7 is getting installed therefore we need to update all these python packages but I am unable to find the pika, webpy , sqlite rpm at any of the repo ? would like to know where we can get the these rpm.

Those packages are all in EPEL for CentOS 6 but not for 7. I suggest that your first step is to search bugzilla.redhat.com and see if they have already been requested for EPEL7 and what the status of those requests are if they exist. If they don't exist then you should probably raise a bug and ask if they can be ported across.

Thanks TrevorH, I have installed from git as its just for investigation , currently only 1 Bugzilla is there for pika not for others. Will raise the bug.

Another dependency issue I am hitting is related to cluster-glue & pacemaker installation. Is there any clue how we can resolve this ?

The program yum-complete-transaction is found in the yum-utils package.
--> Running transaction check
---> Package pacemaker.x86_64 0:1.1.12-22.el7 will be installed
---> Package pcs.x86_64 0:0.9.137-13.el7_1.3 will be installed
--> Processing Conflict: cluster-glue-1.0.12-1.el7.centos.x86_64 conflicts rgmanager
--> Finished Dependency Resolution
Error: cluster-glue conflicts with pacemaker-1.1.12-22.el7.x86_64
You could try using --skip-broken to work around the problem

There is no cluster-glue package for el7. There is no rgmanager either. Don't try to install el6 packages on el7, they will not work. In addition, the entire cluster stack has changed completely in el7 so that it's now pacemaker/corosync/pcs based instead of rgmanager/luci/ricci/cluster-glue. They are significantly different and need relearning.
