Hi. I am using CComments on one site, and am about to migrate JComments to CComments on another site. On this second site, it is a J2.5 site ... then I plan to upgrade to J3+.
Step 1. Migration of JComments to CComments. J2.5.28 site.
Step 2. Upgrade the J2.5.8 site to J3.5+

Here are my questions:
1. I can't find clear guidance in the documentation on migrating JComments to CComments. I have not yet installed CComments and will be doing this migration on a dev copy. If I missed this documentation, that please provide the link. Otherwise, can you explain the steps (or it is a simple task once the software is installed)? This link was not helpful to me: https://compojoom.com/support/documentation/ccomment/ch05s02
2. What is the process for upgrade to J3, so that I keep CComments working and avoid error messages? I have run into issues where the J2.5 install doesn't work after upgrade (with other software). Do I need to take special steps when upgrading from J2.5 to J3?

Thanks in advance, Vicky
