OpenBSD 2.7 was released in June 2000. OpenBSD versions are supported for one year. The possibility of anyone remembering anything about 2.7 is miniscule to non-existent, & there is certainly no longer any official support. There has been no support for version 2.7 for nearly eleven years.
...they do not want upgrade OS...
If neither you nor any other engineer at your company has the skills to do this work yourselves, your only real alternative is to contact a consultant who will do the work for hire. The OpenBSD project maintains a page on their Website for consultants:
Your best bet is to try to convince management that they need to upgrade to a recent version. Sticking with such an old unsupported version as you are doing now means that you
are now responsible for all
support. Otherwise, do the cost analysis to determine if the work is important enough to warrant the costs of a consultant.
