Are you running RM2 on your old computer? If so, just install RM2 and copy your data over. If not, you could still install RM2 if you plan to upgrade, as RM2 will upgrade older RM1 files as it needs to. You can have side by side installations of RM1/2, but note that RM2 uses a different workspace format so you cannot (easily) share workspaces between them,
