Brocade FOS Target Path Version 4.1 (GA-TB-447-03, January 2014)

DATA CENTER TECHNICAL BRIEF
Brocade FOS Target Path 5 of 6
MIGRATING WITH TARGET PATH RELEASES
The following upgrade paths are recommended for customers who are running older versions of Brocade FOS and
wish to upgrade to a Target Path release, in order to avoid the known issues or pitfalls that might exist in some older
versions of firmware. If a switch is already running at a major release level that is different from the specific code
version recommended in the migration path, simply move forward to the next major release level’s recommended
Target Path release, and continue the migration process from there. For example, if a switch in an Open Systems
environment is already running Brocade FOS v6.1.0c, the next step in the migration to Brocade FOS v6.4.2a or
v7.0.0x would be to migrate to Brocade FOS v6.2.2f.
Always carefully review the Brocade FOS Release Notes for both the version of code that you are moving away from
and the version of code that is being installed, prior to performing the new code installation.
Upgrade path to Brocade FOS v6.4.3d/e or FOS v7.1.1a/b for Open Systems environments:
FOS v6.0.0c FOS v6.1.2c FOS v6.2.2f FOS v6.3.2d FOS v6.4.3d/e  FOS v7.0.2c/d
FOS v7.1.1a/b/c
For Open Systems environments already running FOS v6.4.2a:
FOS v6.4.2a FOS v7.0.2c/d FOS v7.1.1a/b/c
Upgrade path to Brocade FOS v6.4.2a or FOS v7.1.0c for FICON environments:
FOS v6.1.2 FOS v6.2.0e_upgrade FOS v6.3.0d FOS v6.4.2a FOS v7.0.0d FOS v7.1.0c
Note: For FCIP FICON Emulation for (XRC, Tape, etc), substitute recommended releases noted in Table 2.
FUTURE TARGET PATH RELEASES
Because the very nature of a Target Path release is that it is based on proven reliability and lack of critical issues, it
is impossible to predict future Target Path releases. However, based on the very mature qualification process and
planned release schedules for maintenance and patch releases, Brocade is able to provide some guidance as to the
main code stream that the next Target Path release is likely to be in.
Brocade currently expects the next Target Path release to be a patch based on the FOS v7.2.1 code level in mid-
2014.
The future Target Path release level and timeframe are both subject to change without notice.
