The crystal version is a mostly a non-issue.
You will never have to redo any of your reports, regardless of what version of crystal you have. I have customers with crystal version 6 running against a 76400a database all day long.
The issue is this: Crystal 76300c and later gives you the
option of installing crystal v10 ICRs. All this means is that if you do take this option, you cannot use your older version of crystal to modify the macola built-in ICRs. All of your old reports will still work and none of the table names have changed.
Likewise, you can buy any version of crystal up to and including XI, and it works on all versions of Macola. Again your only limitation is on modifying built in ICRs and running them through the Macola interface.
Nor is there any "conversion" from any version of crystal from 5 to XI. You open it, you save it, you are prompted to update to the new version, and you answer yes. That is it, you're done.
For the most part crystal reports are not backwards and forwards compatible, so once you go to a version of crystal you should go to it company wide.
