Upgrading from Release 6.x
If you are upgrading from a release earlier than TIBCO FTL Release 6.7.1, you must first upgrade to Release 6.10.1 and then follow instructions for upgrading from 6.7.1 or later to TIBCO FTL 7.0.0.
You can upgrade to TIBCO FTL Release 7.0.0 directly from TIBCO FTL release 6.7.1 or later.
This procedure uses a rolling upgrade, which is to upgrade one server at a time. This lets you upgrade a network without a total service interruption.
Upgrading from Release 6.7.1 or Later
This procedure uses a rolling upgrade, which is to upgrade one server at a time. This lets
you upgrade a network without a total service interruption.
This procedure enables you to upgrade to TIBCO FTL Release 7.0.0 from TIBCO FTL release 6.7.1 or later.
- Procedure
- Determine which core servers are leaders, and plan the order in which you want to upgrade host computers to the new release of TIBCO FTL. A recommended sequence is as follows:
a. disaster recovery location, non-leader core servers
b. disaster recovery location, leader core server
c. disaster recovery location, auxiliary server
d. primary location, non-leader core servers
e. primary location, leader core server
f. primary location, auxiliary server
g. satellite location, non-leader core servers
h. satellite location, leader core server
i. satellite location, auxiliary server - Check the persistence clusters status table and its services list sub-table to verify that all the persistence services in the cluster are a) running, b) part of the quorum, and c) up to date.
- Address the first or next host computer in your plan and stop its TIBCO FTL server process.
This stops all services under that TIBCO FTL server automatically.
- Uninstall the old TIBCO FTL installation package from that server’s host computer. See instructions in TIBCO FTL Installation.
- Install the new release of the full TIBCO FTL product on that host computer. See instructions in TIBCO FTL Installation.
- Ensure that all server computers in the cluster have their clocks synchronized.
- Repeat steps 2-6 for the next TIBCO FTL server in your plan. Continue for each server until you have upgraded all the TIBCO FTL servers.
-
Upgrade all application clients.
Migration With Disk Persistence
Migrating TIBCO FTL Servers to TIBCO FTL Release 7.0.0 from TIBCO FTL Release 6.7.1 or Later 6.x.x versions
TIBCO FTL Server 7.0.0 disk persistence database is different from TIBCO FTL server 6.x.x disk persistence database, hence when you upgrade to TIBCO FTL server 7.0.0, a downgrade to an older version is not possible without the TIBCO FTLServer data directory backup from the earlier version.
Follow the procedure in Upgrading from Release 6.x
Once the upgrade is complete, the old database can be moved or deleted.The old database files will have the suffix ".imported" appended to the file name.
Migrating TIBCO FTL Servers to TIBCO FTL Release 7.0.0 from TIBCO FTL Release 6.7.1 or Later 6.x.x Versions When Provisioned Disk Space Cannot be Expanded
Determine which TIBCO FTL servers are leaders, and plan the order in which you want to upgrade host computers to the new release of TIBCO FTL.
Suppose ftls1 is the leader of the persistence cluster, and ftls2 and ftls3 are followers. This is the recommended sequence
-
Shutdown one of the servers which is the follower (ftls3).
-
Delete the data directory of this server (ftls3) that was just shutdown.
-
Start a TIBCO FTL 7.0.0 server and let it catch up from the other two servers from 6.x.
-
Shutdown another one of the 6.x TIBCO FTL servers which is also a follower (ftls2).
-
Delete the data directory of this server (ftls2) that was just shutdown.
-
Start a TIBCO FTL 7.0.0 server and let it catch up from the other two servers.
-
Once the two 7.0.0 TIBCO FTL servers are fully in sync, shutdown the 6.x leader (ftls1) TIBCO FTL server.
-
Delete the data directory of this TIBCO FTL server (ftls1).
-
Start a TIBCO FTL 7.0.0 server and let it catch up from the other two servers already from 7.0.0.
Migrating TIBCO FTL servers from one data center to another
When you are migrating from TIBCO FTL release 6.7.1 or later where disk persistence is enabled, for data center migration or upgrades, you can shut down the servers and copy the disk persistence related database files for data center migration use cases. You must shut down all servers before copying these files.
Enabling Disk Persistence for the First Time
When migrating from in-memory persistence to disk-based persistence, two rolling upgrades are required. First, upgrade to 6.7.0 (or later), enable disk persistence or disk swap, then restart the servers again.
