Yes. The only requirement is that the client library being used must match the version of the server.
For example, you may have isCOBOL 2021R1 and c-treeRTG 11.9 running on a machine and you want to also run isCOBOL 2022R1 with the same c-treeRTG.
Then you must use the ctree.dll on Windows or libctree.so on UNIX/Linux from the isCOBOL2021R1/bin or native/lib directory with the isCOBOL 2022R1 version.
For example, you can copy /isCOBOL_SDK2021R1/native/lib/libctree.so to your /isCOBOL_SDK2022R1/native/lib directory. Or in Windows copy the isCOBOL_SDK2021R1/bin/ctree.dll file to isCOBOL_SDK2022R1/bin.
Another way to look at this is that on UNIX or Linux, the libctree.so from the isCOBOL 2021R1 version must be in the LD_LIBRARY_PATH, LIBPATH, etc. when running isCOBOL 2022R1.
On Windows the ctree.dll from the isCOBOL 2021R1 version must be the first ctree.dll in the Windows search path when running isCOBOL 2022R1
