Bernie,
In most cases R:BASE will allow two different versions to connect to the
same database. R:BASE Technologies has promoted this functionality to
assist the conversions of databases from one version to the next, and in
some cases two versions apart. This applies when migrating RB1-RB4 files,
and in most cases for when migrating RX1-RX4 files.

When 7.0/7.1 was first released, users could still use the prior version
6.5++ during the conversion. R:BASE 7.5 also supported this dual-version
connectivity. Between 7.6 and R:BASE eXtreme 9.0/9.1 (32) the same dual
connectivity is allowed. With the current release, 9.5 (32), support to use
R:BASE eXtreme 9.0/9.1 (32) during the conversion is also possible.
As with most software programs, waiting too long to upgrade between
versions will result in incompatibility with your files.
In your situation, it was definitely recommended by R:BASE Technologies
that you do not perform the conversion from 6.5 to 9.5 upon a live
database. The structural differences between the databases versions that
were released 10+ years apart are great enough that this approach is ill
advised.
To be clear, version 2.11 and 9.5 cannot talk to the same database. And,
4.5 and 9.5 cannot talk to the same database.
Does this mean the client cannot upgrade? Of course not!
The recommended course of action for the conversion is to convert a copy of
the database in two phases. The first phase is to replicate every aspect of
functionality used in 6.5, and the second phase to implement the latest
features to improve the productivity of the application.
The latest R:BASE release provides more conversion tools to developers than
any other prior version of R:BASE:
. Enhanced DOS to Windows Form Conversion
. Enhanced DOS to Windows Report Conversion
. Enhanced DOS to Windows Label Conversion
. Legacy Application File Conversion
. Ability to search for text in Custom EEPs
. Ability to search for text in control properties
. Ability to search for text in variable names and expressions
. Context Help for Form, Report, and Label Designers
. Single Click Form Object Conversions
. Additional Data Dictionary Features
. Copy/Paste Pop-up Menu Properties
. New Favorites Toolbar for Form/Report Designers
. Enhanced "Find in Files" keyword search utility
. New R> Prompt Enhancements (Command History Panel)
. Column Comment Hints in WHERE/Expression Builders
. And more...
Educate yourself on these many helpful features in the new version.
Rely on the existing time-tested features that have been built into R:BASE
for years:
. R:BASE Editor
. R:Style
. Data Dictionary
. Trace Debugger
. Themes
. BLOB Editor
. And more...
Waiting is no longer an option. The time is now!
Respectfully,
John
