Version of sync.ffs_db database

[Anonymous]

Is it possible to find out what version of FFS was used last time (version of
sync.ffs_db in the automatic mode)?

The problem is that the database format changes between versions and the FFS
synchronization of original version is needed before using a newer version of
the GREAT tool. I am still using version 3.6 because I cannot update all
synchronized locations at a time and I cannot afford losing the
synchronization information because of changed database format.

Technically it's possible, but the version id is stored at the beginning of a
gzip compressed stream. So the most practical solution is probably to open and
compare the directory with a recent version of FFS and check if an error
message comes up.

The problem is that in automatic mode using any newer version of FFS (e.g. 4.5
whereas database was created using 3.6) causes creation of duplicated files if
a file name was changed on either side and restores all deleted files. The
workaround is to synchronize two folders before upgrading the tool, but the
question is what version of tool use to sort out all differences before
upgrading.

There has been only one change in database format in v4.3. So you can use two
versions of FFS v3.6 and v4.5. If one version reports a warning "incompatible
database format", then use the other.
