We are using alfresco community 5.0 and the PostgreSQL DB using(bundled with Alfresco standalone installation) is
PostgreSQL 9.3.6, compiled by Visual C++ build 1600, 64-bit.
We are suspecting that the PostgreSQL is slow and this version is so old, can we just upgrade this DB to latest PostgreSQL , which is PostgreSQL 13.4.1 ?
Should have no data lost after that ?
if the upgrade answer is a no, what version of PostgreSQL 64 bites we can upgrade the DB to ?
and if we upgrade in this manner, will it case any problem when we upgrade our existing Alfresco community 5 to:
1) Alfresco community 5.2
2) Alfresco community 7.0
3) Alfresco enterprise ?
Network and collaborate with thousands of CTOs, CISOs, and IT Pros rooting for you and your success.
