In addition, on Mac OS following formats are no longer supported: IFF Format, Photoshop 2.0, Alias PIX, PICT Resource.JPEG 2000, Filmstrip (FLM), Wireless BMP (WBM, WBMP), PCX, Targa (TGA, VDA, ICB, VST), Photoshop RAW (RAW), PICT File (PCT, PICT), Scitex CT (SCT), Photoshop EPS (EPS), EPS TIFF Preview (EPS), Generic EPS (AI3, AI4, AI5, AI6, AI7, AI8, PS, EPS, AI, EPSF, EPSP).Following file formats are no longer supported in Photoshop Elements 11 and the corresponding files will not be imported into the new catalogs.Updating previous catalogs (more than 30,000 photos) can take over an hour (possibly a few hours, if the catalog is large, and from an older version of Photoshop Elements or Photoshop Album).If you use multiple catalogs, start Photoshop Elements, go into Organizer, and use the File > Manage Catalogs command to search and convert other catalogs. Only the most recently used catalog will be converted automatically.Catalogs created in older version of the product would need to be converted to the latest version.

Although it is not necessary to uninstall any previous version of Photoshop Elements, Adobe does not recommend switching between older and newer versions of the Photoshop Elements Organizer.
