This topic describes compatibility of projects between
the latest version and V8.0.x and V7.5.x
To be compatible with version 8.5.x , projects
created in version 8.0.x and version 7.5.x must be migrated to version 8.5.x. For details
on migrating projects to version 8.5.x, see Migrating workspaces and projects from version 8.0.x or version 7.5.x.
Compatibility of migrated projects with earlier product
versions
This section describes the compatibility of a project
(or other artifact) to work with earlier versions of the product.
- Projects migrated from version 7.5.x to version 8.5.x are not compatible
for sharing back to version 7.5.x.
- Projects migrated from version 8.0.x to version 8.5.x are compatible
for sharing back to version 8.0.x.
Projects migrated from versions earlier than version 7.5.5.1 with
interim fix 1 will not be compatible with that version after migrating
to version 8.5.x.
Note: To
maintain compatibility, you cannot use features available in version 8.5.x that are not
available in version 8.0.x.
The
project must have a target runtime that is available in both version 8.5.x and version 8.0.x.
The following table summarizes the compatibility of projects
migrated to
version 8.5.x with
earlier versions

For some types of projects, you might see warning messages
if you open a project in version 8.0.x that has been
migrated to version 8.5.x.
See Opening projects migrated to version 8.5.x or created in version 8.5.x in version 8.0.x might cause warning messages for more information.
Migrated workspaces are not compatible with earlier
versions
Workspaces migrated to version 8.5.x cannot be opened
it again in the version it was migrated from.
Compatibility of new projects created in version 8.5.x with version 8.0.x
New
projects created in
version 8.5.x are
backwards compatible with
version 8.0.x under the following
conditions:
- The new version 8.5.x project
must have a runtime target that is available in version 8.0.x.
Note: If
you open a project in version 8.0.x that was created
in version 8.5.x, you
will get error messages that the target runtime is not defined. This
error occurs even if the target runtime is available in version 8.0.x. If the target
runtime is available in version 8.0.x, then resolve
the problem by clicking and selecting the target runtime that was identified
in the error message.
- The new version 8.5.x project
cannot use any features in version 8.5.x that are not
available in version 8.0.x
For some types of projects, you might see warning messages
if you open in version 8.0.x a
project that was created in version 8.5.x. See Opening projects migrated to version 8.5.x or created in version 8.5.x in version 8.0.x might cause warning messages for more information.
Note: If
you open a project in version 8.0.x that was created
in version 8.5.x, you
will get error messages that the target runtime is not defined. To
correct the problem, click and select a target runtime for the project.
Opening projects migrated to version 8.5.x or created
in version 8.5.x in version 8.0.x might cause
warning messages
Some types of projects that are migrated
to version 8.5.x or created
in version 8.5.x can
cause warning messages if they are opened in version 8.0.x. The warning
message says there are "missing builders" or certain project facets
cannot be found. These messages occur because the project contains
metadata specific to version 8.5.x that
does not exist in version 8.0.x.
These messages are expected and can be ignored.
