Upgrading BMC Remedy ITSM 7.0.03 patch 009 or later applications to BMC Remedy ITSM 8.1

Unknown macro: {multi-excerpt}

The BMC Remedy ITSM 8.1 installer supports upgrading from the BMC Remedy ITSM 7.0.03 patch 009 or later to BMC Remedy ITSM 8.1.

Before you begin

Before you begin, please consider the following:

When upgrading from BMC Remedy ITSM 7.5 with Search server to BMC Remedy ITSM 8.1 or later with Lucene FTS and FTS HA, you must ensure that the fts_pending table is empty before you begin the upgrade. Search server is not compatible with Lucene FTS and FTS-HA. If you do not empty the fts_pending table, indexes are not created when you run the following SQL query:
```
CREATE UNIQUE INDEX ft_pending_ind ON ARADMIN.FT_PENDING
```
After a BMC Remedy ITSM 7.0.03 patch 009 application is upgraded to BMC Remedy ITSM 8.1, do not install BMC Remedy ITSM 7.0.x applications on that BMC Remedy AR System server. Doing so will downgrade BMC Remedy ITSM 7.6.00 foundation data.

BMC Remedy AR System Server 7.6.04 introduces the Best Practice Conversion utility, which enables you to convert pre-7.6.04 customizations in BMC Remedy AR System components and applications into overlays or custom objects. Overlays and custom objects ensure that your customizations are not lost when a BMC Remedy AR System application or server is upgraded.
Recommendation

Run the Best Practice Conversion utility prior to performing an upgrade.
For more information about the Best Practice Conversion utility and overlays, see Creating overlays with the Best Practice Conversion Utility.

As of BMC Remedy ITSM 7.6.03, BMC Software has replaced the CAI, ARDBC, charge backs and NextId plug-ins written in C with Java plug-ins in order to enhance performance. For more information, see Manually registering application plug-ins.
