That really depends on several factors:
· What does your architecture look like (EM plus multiple DMs, single DM, remote vs local MDBs)
· Is your architecture still suitable for your environment?
· What version ITCM are you upgrading from/to?
o Direct upgrade may not be supported, you may have to perform a 2-step upgrade or a migration.
· Is your EM/DM hardware still sufficient?
o May need to build new EM/DMs and migrate
· Are the OS and SQL Server versions on your EM/DMs still supported (both by MS and by the current ITCM version)?
o May be easier to migrate than perform a complex multiple OS, SQL and ITCM upgrade
CA Services will be happy to assist with your upgrade/migration of course, but if you wish to do it yourselves CA Support can help you evaluate your current environment and decide on an appropriate strategy.
