Good news for you FDM Classic users out there looking to extend the life of legacy FDM just a little longer. Oracle has provided a solution for using FDM Classic with IE11. See My Oracle Support Knowledge Base article Doc ID 2028236.1 for details.
Keep in mind, if you plan an upgrade to Oracle EPM Release 188.8.131.52, you will still need to migrate to FDMEE. There’s no sticking around with FDM Classic beyond Release 184.108.40.206. And with 220.127.116.11 being the second major release of FDMEE, there are a lot of reasons to make the leap to FDM Enterprise Edition. Want to know a few of those reasons? Click here.
