By default the Shared Database stores documents in the latest document format the same way the Local Database does. This can cause compatibility problems if diﬀerent sets of users are using diﬀerent versions of Geneious. For example if a user on Geneious R11 saves a new alignment document, users on Geneious R9 will be unable to read those documents.
To get around this issue the Shared Database can be conﬁgured to save documents in a format speciﬁed by an older version of Geneious if that version is still supported. In most cases this will allow for users using Geneious 8.1 or later to seamlessly share documents with users of any version back to Geneious 6.0. However be aware that if the document format has changed since the compatibility version, then users of the newer version may ﬁnd their documents missing properties or bug ﬁxes that have been added since the format changed.
The Document Compatibility Version setting will apply to all users using the database with Geneious 8.1 or higher and can only be set by a Database Admin. You will ﬁnd this setting by choosing Administration in the shared database context menu (visible when you right-click on the database root folder) and then Set Document Compatibility Version.
For Direct SQL Connection Shared Databases, document size is limited by the underlying database system. Talk to your system administrator if you work with very large ﬁles such as contig assemblies and complete genomes.
Geneious Server Databases have no limits on document size, and performance with large documents is signiﬁcantly better than with Direct SQL Connection Shared Databases.
