Terracotta Server Migration from BigMemory to Terracotta
The new generation of Terracotta Server and platform has very significant changes from BigMemory with respect to handling of cluster topology, data storage formats, and various other aspects.
Because of this, there is no possibility of direct migration of data and configuration from a BigMemory installation to a Terracotta installation.
If you intend to reuse the same host systems in Terracotta that you were using in BigMemory, the Terracotta Server configuration file(s) from an existing BigMemory installation may be a useful reference when you create your new Terracotta configuration file(s). The BigMemory configuration file(s) contain the host names, addresses, etc. that you have been using so far.
